Custom exhaust tails
 
How much should a custom set of header tails run? I have an 500efi and planning on running CMI sport tubes.

Depends on length and angles.........bravo boat ?

EMARTELL65 09-21-2019 02:45 PM

Bravo boat with an s bend. I want to replace my current setup to dress it up a bit.

Likely 2-3k through CMI. Install the headers and then mock up the tails with PVC

EMARTELL65 09-21-2019 02:59 PM

I might mock them up like you suggested with pvc and fab them myself. Thanks!

F-2 Speedy 09-21-2019 03:19 PM

Nice. I’d Like to make it to the Ozarks some day for the shoot out.

You have Stainless Marine with nice risers.... DON'T TOUCH IT !!!!!

Performance wise you have good exhaust... Dependability wise you have good exhaust, A little extra bling is not worth header headaches. Do a search on here for cmi/header cracks/leaks......

You want bling?? for what you would spend on headers which are going to net you zero performance wise, you could stick a say, 250 blower on it and actually gain some performance

Thanks for the feedback. In other words save the money.

Save yourself the headaches and keep the SM . You really won't see any gain in speed to justify . I assume you have a platform on the back as to why they are fabed like that. The cost of tubes you should be able to bling out the bilge . Wait until holidays and Teauge has great sale on the pieces they manufacture, Scored my 3 trim tanks last year and 25% off went along way to buy other pieces.

X3...keep the SM. we took our CMI off for improved reliability of SM.

Thanks for all the great feedback. This is such a great forum. I would like to find a complete 500/525 accessory drive set up to covert my v belt to serpentine like your 500’s. The Volvo 500 sea pump is all the way at the bottom on the crank which makes it hard to add a supercharger.

https://www.crowleymarine.com/mercur...cfm?mdl=TVT6XQ . You will need to get a 807767t idler bracket as the one listed in the link is nla. Don't think you will find a used 500/525 pulley system complete.
