I have an 04' wrx and i am looking to put on a turbo back exhaust. I have looked at Xcceleration.com and they have a turbo back , 2 cat ,3" exhaust that has a 5" tip for $1099.00. I was worndering if this seems good or if any one has a better suggestion. Also i don't want cel, and this system says its ok. Thanks for any help i'm just starting out. also any other power mods recomendations are good to.

 

do u want the cats?? and 5inch tip is pretty big...uhm...other than that u can always peice together your turbo back and still wont get a CEL if u do the fixes for it.

 

smaller tips = better

 

A good choice if you want to keep two cats in your exhaust. Probably not the most ideal system for making the most power, but if you have a conscience about polluting then it's your best bet, if you don't you can probably find a more freeflowing exhaust with one cat and then get a MIL eliminator for the CEL.

edit: 5 inch is pretty damn big, I'd personally look for a different cat-back.

 

slack, when you say not the best choice for max power, are you saying not above 300 engine hp or what. my 04' mods will probably stay light for now. I also don't know if turbo back is what i need. maybe just a catback? thanks for your help. further comments wil be appreciated.

also not really worried about pollution, look a gas mpg on the wrx

 

www.msr-usa.com I have the C.E.S. racing systems "street" edition and it kicks some serious @$$! Check it out.

 

You'll get a few extra whp with a 1 cat system or a catless system, the more HP you push the more the cats will become a restriction. Personally I think it is irresponsible to run completely catless, keeping 1 cat isn't going to make much difference in your HP.

If you are looking at a just catback, don't expect much as far as power gains, maybe a 5 HP.

 

i disagree. the HKS makes a lot more than 5 HP. as does a lot of other cats.

 

Yeah i agree with escaflowne the in Turbo Magazine's dyno testing the HKS system had i think a peak hp of 13 or 15 i forgot, but alot of the other catback exhausts made atleast 10 to the wheels.

 

get rid of cats!!!:banana:

 

Is anyone here using the Borla Header .. I saw it on there website but haven't heard anything about it .. Is it worth the $500

 

check out the vendor forum. Helix has a new CATBACK. pretty sweet.
