Hey i want a performance exhaust what should i buy a new performance cat and a flowmaster? how much Hp woudl i gain? How would it sound? about how much would it cost for parts because i have it installed for free

Magnaflow/Carsound High-Flow Cat off Ebay 50-60 bucks

Mufflers depend on what you get, a flowmaster 40 series is about 60 bucks i think, and the 80 series(most people here have these) is a little more expensive.

the muffler you want would be the one for a camaro/firebird with the 3.8...its essentially the same setup, 2.5 inch inlet with dual outlets

as for HP gains...id say maybe 20 at most? really the exhaust manifolds are the most restrictive thing on these cars...headers baby!

as for sound

here is a link to a thread featuring my Magnaflow

and our old pal BonneMEMN has a lovely collection of Bonneville sound clips for your listening pleasure found here http://www.bonneville.fearthepearl.c....php?page=mods

and that reminds me, BonneMEMN if you want to use my sound clips feel free, i know you dont have any for an SE, or for a Series 2 Magnaflow, the files are still hosted on my site even if you just want to link to them or whatever

Here'* a link to my exhaust: Flowmaster Series 40

you can't expect more than maybe 2hp from just a muffler

I just installed a complete Magnaflow system on my 1995 SSEi. I love the sound and also there is an improvement on performance too. I installed the Magnaflow/Carsound converter, Magnaflow resonator and F-body muffler. I got a great deal for all the parts from www.justmagnaflow.com
