Does any know or have a link to an exhaust comparison. I'm wondering what exhaust make the most power gains. Looks and sound aren't a factor, just performance. Also, I'm looking for a turbo back with no cats. Thanks for any help

 

From what I've read and experienced, the Buschur Race Exhaust seems to be among the (if not the) best in this regard. It's quite loud, but it's basically as straight and basic as they come. the catless with the race muffler would be your choice.

 

BUSCHUR is the best but it is loud but i love it

 

Thanks for the reply's, I'll look into the Buschur. Its what I have on the dsm, but I've heard alot of hype about the helix on the evo's so I thought I'd ask

 

Just another quick question on the buschar: Is thier a actual turbo back kit, cause I see all the different pieces, just no kit or even an 02 housing?

 

The main difference from what I hear between the Buschar and the Helix is:
1) Helix is polished and Buschar is not (how often do you look under your car?)
2) Buschar is lighter than Helix
3) Buschar got top honors in a magazine exhaust shoot out (do a search)
4) Price is within a few $100 from each other

Besides weight and appearence there isn't to much between them. As far as horse power I don't think it has been proven which produces more. But Buschar has independent documented proof that there's produces good HP!

 

Does replacing the O2 housing with a new Buschur one gonna make a difference or is the one on the car good enough for a full 3" exhaust?

 

I heard that replacing the factory O2 housing with an aftermarket one will decrease the amount of time for spool up of the turbo. By how much is dependent on your other components & tune I think, but I would guess a few 100rpm difference in spool time.

Do a search for the O2 info...I believe it has been discussed in other threads.

 

if you dont care about sound, go with the buschur, because it is LOUD, at WOT it can be heard from quite a distance, i hear good things from helix

 

go for the buschur tbe with the magnaflow muffler. Half the sound with almost the same performance!
