Turbo Exhaust

[2000aleroff]

After I turbo the alero i was wondering what would sound/look best in the way of exhaust.

I was thinking of either cutting it off at the cat or maybe running a custom set up to the sides... i might just leave it the way it is. any FACTS that will help me?

Keep the cat.

straight pipe from the turbo downpipe...

ya i was thinking a strait pipe too

[kwhauck]

have you ever looked underneath your alero? unless you hang your exhaust low and go underneath the rear axle there is no straightpiping that can be done.......

[2000aleroff]

i thought about that, wasnt sure if it would work. guess it wont =/

Lose the cat. Use a Dynomax Super Turbo muffler.

Just pipe sounds horrendous (IMO) lol. I'll have some sound clips of mine (although 2.4), I have my exhaust cutout open so I'm running open downpipe.

What did the world do to you?

losing the cat is really unecessary.......

After having mine plug up, I just like the assurance that nothing is restricting anything. And turbos love open exhausts.

All tests done on 2.5" diameter units:
Stock LS1 268.3 CFM
Catco (metal core) 271.9 CFM
TTS Bullet 277.1 CFM
Carsound 372.7 CFM
Catco (std. core) 388.0 CFM
-------
Test pipe 498.0 CFM

less restrictive the better....

that's an ls1, lets see some alero tests.....with 2.5 or 3 inch with the difference between a high flow and no cat.......

It's a catalytic converter flow test, not the entire exhaust system. Who cares what it's on? The LS1 just means it was a stock cat off an LS1 equipped vehicle, but the rest are universal items. I just wanted to throw up a stock comparison of a typical car.

ok thinking the whole system,

regardless, i want to see some tests with some high flow cats like a flowmaster, magnaflow, etc....
