Upgrade to performance exhaust

[Guest Turtle9]

i presently have stock exhaust and my header bolts on passenger side are busted. i was thinking on puttin in a performance exhaust(maybe 3") with high flow cat and high flow muffler..

does anyone know what size piping the stock is?? and also do i need to do the whole exhaust system from Headers to muffler.. im a newbie.. so any help would be greatly appreciated...

Hey there Turtle9. Ok, you have a 94 A/T. Stock exhaust after the y on my 95xe is 2". You don't have to install headers, although that will give you more power... You can just replace the exhaust studs, and put in a high flow cat and muffler. Most people seem to go with 2.25" or 2.5" pipe; 3" is probably overkill for a choked 3.0 liter V6... Questions are if you have $ for the headers (recommended) and if you live in a smog strict area.

mine busted too, i got the thoreys, on backorder for a month. if you want them, order now and get in line. 2.5 is big enough.

I think that I am going with Thorleys and a custom 2.5 exhaust with Spintech high-flow cat and Muffler:

Check out my entry in this forum. I have links to the headers on Summits Site.

There has been a gazillion write ups about the exhaust and headers on NPORA forums... with prices, part numbers, sizes, fit, pics, install tips, etc... search... it's worth it!

3" is severe overkill for any NA 4-6 cyl. youll lose tremendous low end torque.

I had a long chat with the Muffler guys today.

 

We came up with a plan of attack on the exhast challenge.

Currently the drivers side header is as far as we can tell stock, the passenger side has a junkyard oem header with one broken stud.

 

Based on him knowing that I can license in a non inspection county, new custom exhaust from the headers back. Appointment set for the 31st. Estimated cost $250 to $300 FlowMaster and all :cool2:

 

He also mentioned going through the injectors and cleaning/replacing/upgrading. 130k miles may be worth it, one step at a time.
