Best brand of exhaust tips?
 

What is the best brand of exhaust tip to buy? Im thinking of buying regular or extra long 4" angle cut tips. I heared some have a wierd noise when its ideling

Re: Best brand of exhaust tips?
 

We have them in stock with or without flappers. Flappers rattle at idle and can be a bit disconcerting but you get used to it.

With Flap: List $ 79.95 OSO price $ 57.40

Without Flap: List $ 64.95 OSO Price $ 49.95

Call or email me if you're interested.

It is a noise that takes some getting used to.

Re: Best brand of exhaust tips?
 

what if you dont use the flapper?

Re: Best brand of exhaust tips?
 

You run the risk of getting a surge of water up the exhaust & damaging the engine.. Unless you have high & dry exhaust run with the internal flaps.. :) J

Re: Best brand of exhaust tips?
 

Does the length of the tip have anything to do with the sound?
Jamie I will be calling you next week about the diverters and the tips!

Re: Best brand of exhaust tips?
 

Cool.. Actually the length has little to do with the sound. The water that flows thru the exhaust & any baffles is what makes the major difference in power & sound.. The less water flowing thru & the less baffleing the more power it can potentially build and louder it can get.. :) Jamie / lakeside

Re: Best brand of exhaust tips?
 

By the way our 2 biggest selling tips are the Eddie marine & Corsa tips.. We have some others as well, but those 2 are usually the most common.. :) Jamie / Lakeside

Re: Best brand of exhaust tips?
 

The sound is the flap rattling on the pivot pin. The flaps are metal with a vulcanized rubber rim. You can get tips with rubber flaps that make no noise but the flaps burn away. The rattleing isn't all that bad but most guys notice it right away.

Like Jamie said, the water makes the biggest difference in sound. The length is all about the look and is limited by the hight above the water line. Longer tips look more old school in my opinion (and I like that look).

A little vid.... lets see if I can get this in.

Just warming up. You can't hear the flaps from the outside but if you open the hatch up and stick your head under it gets noticable.

Re: Best brand of exhaust tips?
 

awesome, sounds great! Thats what im going for

Re: Best brand of exhaust tips?
 

Thanks, it's got the right rumble.

Re: Best brand of exhaust tips?
 

I thought Rex Marine advertised some tips that don't rattle at idle with some type of guarantee. Might be worth checking out! Steve

Re: Best brand of exhaust tips?
 

If you have CMIs, no exhaust tip needed. Just add flappers!

Re: Best brand of exhaust tips?
 

You are correct. The Superflapper™ is guaranteed for life even on blown applications. They do not rattle like our older no burn style flappers that pivoted on a 3/16 shaft. Those were pretty noisy particularly with a large cam. Others that copied them still make them. There are still rubber butterfly flaps on the market, which we stopped making a decade ago because they burn off.

The Superflapper™ rotates with the 5/16" shaft it's mounted on in special hi-temp bushings. It bolts to the shaft too so if it ever requires replacement no welding is required which was not the case with our older no burn flappers. Here's a link.

Also our tips are made out of 316L tube, not 304 or rolled sheet. And they're .083 wall thickness, not .065. 316L is more corrosion resistant than 304.

They're more money than the other tips mentioned. There's a reason. Most of the reason is in the flapper. If I can help please let me know.

Re: Best brand of exhaust tips?
 

I have been looking for tips like that as well (rex marine) but here is the question. I have a 2006 42 Ex Fountain. and it looks like they mount the tips from the inside and have a black trim rim only on the outside. Now who can tell me how or what tips I need, with the correct angle of the exterior mounting flang so that I can go with longer angel cut tips??? I love the old school look also..BZ

I love the look of the SST142's.....

Re: Best brand of exhaust tips?
 

Bob the 142's are our standard lgn tip (most popular) but a lot of the larger boats (like Fountains) use the 152's also (just longer). All our tips have a countersunk flange (6" od) which can be screwed on from the outside (ok) or thru-bolted with nuts on the inside (best). There is no ring required on the inside. The vast majority of the time straight flanges are the way to go. We build very very little 12º flange stuff, in fact I normally only build them special order any more. Your transom is likely already in the 12º range.

The tips you've likley seen with the black rings are similar to the style we supplied Fountain with for years that have no flange welded to the tube. They used and oring sealed flange they made and just slid the tube through it. The only advantage to doing that is you have a little fudge room as far as angle of tube through the transom. We make stainless flanges with silicone gaskets you can do that with also. I could supply a 142 or 152 tube with Superflapper™ along with that style flange/gasket. For that large a boat I'd go with the 152 longer tip to achieve that old skool look. We can also supply straight ended tip (SST127) same as above (also a 15" long tube).

Feel free to contact me for more info. Thanks

Re: Best brand of exhaust tips?
 

Bob,

There's your answere! Rex did fix the rattle problem with the tips. I've seen a few in use and the guys running them seem to be happy.

Re: Best brand of exhaust tips?
 

you got mail...BZ

Re: Best brand of exhaust tips?
 

Can just the flappers be replaced or do you need to purchase the whole tip assembly?

Re: Best brand of exhaust tips?
 

Yes the flapper itself can be replaced. Ironically we've only replaced a couple out of several thousand in service now. We've had these now for going on 5 years I believe.

The older style were not only noisy at idle but the shaft was too light (3/16) and several just broke the shaft off at the weld, particularly on motors with large cams. We've retrofitted a lot of the older No Burn Rex tips with the new Superflappers™. If anyone has older Rex tips with broken flappers we do upgrade them. Unfortunately other brands (still being sold) don't fit our fixturing due to the thinner tube so we can't put SF's in them.

We can also upgrade the real old ones (Rex brand) that had the butterfly type flapper.

Bob Z I will give you a call. Was out sick Friday which sux.

Re: Best brand of exhaust tips?
 

Question for Rex Marine...Any discount for OSO members?:D

Re: Best brand of exhaust tips?
 

I guess I should have asked if I could buy the flappers
and install them in my tips to replace the originals?

Re: Best brand of exhaust tips?
 

I'd be more concerned about my exhaust than tips...

Re: Best brand of exhaust tips?
 

Thanks for the useless information pantera!!!!!

Re: Best brand of exhaust tips?
 

We have to install the flappers here as special fixturing is necessary to punch holes, locate, weld the bushings into the tips for the Superflappers™. I can only do this on Rex tips as mentioned above due to our thicker tubing. Thinner tubing type tips don't fit our fixturing properly.

Re: Best brand of exhaust tips?
 

rexone, I have your tips from late 80's early 90's can't quite remember but they are Rex. 4" to 3.5" slash cut stainless. The orginal flappers burned out after the first season. What's the cost of a retrofit? Any warranty if they blow out?

Re: Best brand of exhaust tips?
 

If they're from that era they could be Imco tips which are thinner rolled sheet metal meterial (rolled from flat stock and seam welded, not tubing).

We did not start manufacturing our own tips until roughly 1992. Measure the wall thickness. If it's .083 they're Rex tips. If it's around .065 they're Imco tips. If they are 3.5" tubing they're definately Imco's because we never built any 3.5" diameter other than reducing the 4" with reducers.

That's the first step to see if we can retrofit. Just let me know.

To answer your last question the new Superflappers™ are guaranteed for life. thanx

Re: Best brand of exhaust tips?
 

That was my thoughts too.

But I guess not.:(

Re: Best brand of exhaust tips?
 

tt Rex, for my Fountain 4 X $119.00 is that expensive????? BZ

Re: Best brand of exhaust tips?
 

It may be pocket change for some, but since I'm a blue collar guy with white collar tastes, I watch what I spend and save that for gas money.

Re: Best brand of exhaust tips?
 

Got Rex!

The quality is much better. I don't expect these to blow out. They still rattle a little though.

Re: Best brand of exhaust tips?
 

imo yes they are expensive. But I never intended to build just another cheap tip with an inexpensive flapper that just burns out or breaks off, when I designed the Superflapper™. Cost was of secondary concern. Not of no concern, but secondary to quality comprimise. I just wanted a product I could sell with the confidence I would not be seeing the flappers come back broken, would not continue to get phone calls about noisy flapper rattle, on and on. This while maintaining the highest quality in terms of materials, quality of polishing, and workmanship. I feel we've achieved that goal with these current tip models. Our polishing for example consists of pre-polishing the tubes and flanges, welding, then final polishing. Any tip with pit's or scratches that won't polish out are rejected and sold as seconds. We inspect all our parts under florescent light, the harshest test. The florescent light test results in rejections that are not even visible in sunlight in many cases. I'm very anal when it comes to this stuff and my guys know it and reject parts for my final inspection on a regular basis. The same process holds true for all our stainless parts whether it be crossovers, thermo housings, cleats, whatever... they all go through this polishing and inspection process.

I know when a pair of exhaust tips go out the door now the customer is going to be happy with the quality and won't be calling me within a year regarding flapper issues. We also guarantee that flappers for life which I mentioned above. There are a lot of cheaper tips out there, in fact we are probably the most expensive of them all I'd guess. I simply can't even build our tips at this quality level for the cost some others on the market are being sold for. It's like everything in life I guess. There are cheap cars and expensive cars, cheap boats and expensive boats. You just have to decide which quality level you want.

Hope to hear from you BZ, you won't be dissapointed with the quality.

Re: Best brand of exhaust tips?
 

All of the Hardin Marine tips feature the new Silent Seal exhaust flap design eliminating annoying sound of the clanking stainless flapper. Click here for pics and more info

Re: Best brand of exhaust tips?
 

Call me...BZ

Just installed my exhaust tips I got from Fionn
they look and sound great!

I thought you had to run a dry exhaust with big cams due to reversion.

Michael

Lookin' good!

Glad you like them, now let's see that boat in the water. ;)
