89 Pachanga 383 stroker exhuast question?
 

Hi I am new to the forum and new to the boat I just purchased. I have have been reading and checking out the whole forum and love what I see. I just purchased a 22' pachanga and i cant wait for warmer weather.
Now for my question. I was woundering if any one could tell me how to make the exhaust louder. I read on here that you can buy 4" or 4 1/2" stainles 90's and just hook it up. Do you need internal exhaust flaps to prevent water rushing into the motor? And would it sound good like all the other small blocks with thru hull? If any one one has a list of the stuff I would need it would be awesome. Does any one have pics or video?

When I had my 22 I never removed the mufflers, I have heard them without and the sound is not as good as what the twins in my 32 sound

really? I wish someone had a video.

Have you taken the boat out yet?

Honestly, drive it around for a few outings, you might not want to deal with how load straight pipes tend to be. The P22 has a good mix of sound and not being too loud...

Oh I will in about one week. I dont want it straight thru. I was thinking about putting a 4" 90 on to make the bend and then a inline silencer.http://www.cpperformance.com/detail.aspx?ID=351 I just dont know If I would need inline flappers for rushing water purposes. I think it would sound better and a little louder than stock. Not sure tho.

My 22 with the mufflers sounded really good, I didn't realize how good it sounded until I was riding on a tube behind it, could have rode all day listening to it

So your saying you want it louder but haven't take the boat out yet?

Honestly, sea rays setup is a nice balance between sound and loudness. I personally wouldn't change it.

I did it to my 1988 22 with the fiberglass 90 degree elbows and I hated it sounded like a old truck with no mufflers plus water inversion is a issue, just run it and enjoy it nice boat them P22's!!

Ok thanks for all the comments and oppinions. I cant wait to go out this year. Is there any other good mods to do to a pachanga? Performance realated.

here's the exhaust tips I added to my boat last yearAttachment 412675http://i840.photobucket.com/albums/z...Picture017.jpg

I like that flamingo.. Was that easy to do? I was thinkin about upgrading headers insted of worrying about the exhaust sound.

It wasn't that hard to do, just time consuming. The hard part was getting the balls to cut into my boat !!!

Ha I bet dont no if i could do it.

Heres the exhaust upgrade, I added the stainless risers, made the stainless collectors and relocated them to the rear of the motors.

Very nice Flamingo!!!:Score-101010:

27.... did you get your boat wet yet ??

She is going in on Saturday next week knock on wood!

Got out on the Bay this weekend and the new exhaust sounds great!! picked up 2 mph and 300 rpm into a headwind with less than ideal conditions

That rules!!! Good seeing you Friday looks even better in person!

Thanks.....had a pretty good time, felt like summer on the docks

Flamingo 32 just sent you a message

On my P22 I have stainless marine exhaust without the mufflers. sounds pretty good. Here are some pictures of the exhaust. The second picture shows the elbow in the back. Its not quite a 90 degree elbow. I can take some better pictures if you are interested. I have a video of the boat idling on the trailer and a video at speed. here are the links.

http://www.offshoreonly.com/gallery/...haust&cat=3117I purchased a P-27 mid-season last summer and had about 10 hours of use prior to getting water intrusion in one motor. I took it to my local marina who diagnosed a cracked head. They replaced the head (with a re-built head) I also had new exhaust manifolds, risers, and elbows installed. After the work was done, I water test it, but the weather only permitted a short run, maybe 10 minutes and all seemed fine. Needless to say with less than an hour of total run time on that motor it blew up.

FWIW-- I wanted to take it out for a longer run to shake it down but wasn’t able to get back to the boat for about 2 weeks after that initial 10 minute run. The next time I went out, I ran it for about 10 minutes, basically idling between 1,100 -1,400 RPM’s through the “no wake” zone on the way to the local gas dock and then off for a shakedown… After getting gas, I was cursing at 3,200-3,400 RPM for about 10 minutes and then the RPM started to drop and within 15-20 seconds the motor shut down… The oil on the dipstick was black and smelt burnt. When I got back to the dock I pulled the valve covers off to find a very loose rocker arm. When the guy who did the work looked at it, he said it was nothing to do with the head and the motor had water in it again and busted a connecting rod. Anyway, the reason I’m posting this here. He/the marina feels the water intrusion is due to the way the pipe that runs between the two elbows dips inward. I’m not sure I agree with this…

The boat lived most of its life in fresh water and everything seemed original. I asked the prior owner if he ever had water intrusion/ ingestion and said he never had any issues of water intrusion (I want to believe the P.O. and he has no reason to lie, at least not at this point). Anyway the shop/marina suggest I have the pipe cut and welded so it dips outward vs. inward. I would like to hear some opinions from others who have done exhaust work on the boats. Also, if you think the pitch of that pipe should be changes, maybe you have some suggestions as to a more cost effective way to deal with this issue.

Thanks in advance…

Bud, start a thread of your own. It's OK to reference this thread but you should have your own thread.
To answer you, the starboard collector end appears to be above your exhaust, That's no go. You need downward slope so you won't get reversion. Also are you running hot cams? They will have a major affect on reversion too. Stock is least reversion, but why do that unless your engine came that way and you haven't had a chance to correct it yet.

no reversion problems with the stainless marine set up I have
