i need help deciding on what exhaust sytem i should get. i have read that some downpipes decrease power?? so im wondering if i should only do a cat-back or the whole turbo back. Also, i wanted to know what i should do because i still want to use my o2 cencor, but by changing the cat to a test pipe/offroad pipe i cant do that. is the high flow cat still pretty restrictive? which company would you recommend?

 

I have a RMR catback, downpipe, UR 3" high-flow cat, and a K&N filter. Went on the dyno and gained 28 more whp on DynoLog dyno (which is equal to about 35 more whp on a DynoJet).

 

i have import tuner in front of me and it says that the rs*r down pipe losses like 4.5 horse.

 

it all varies on what kind of set-up you got on your car,with an intake/dp/catback/high-flow cat or cat-delete on the car should be perfect w/o losin power not unless you have a 93 octane then it will be different since here in cali we only got **** gas(91)

 

I have the UR 3" downpipe and cat delete with the AMS catback.

 

Where have you received the info on losing power with a down pipe?

 

How did you guys (specially the RMR downpipe) reinstalled the lower tie bar? I need like 1/14 inches of washers to put mine back.

 

Get a HKS or the RMR downpipe. Ive never heard anyone complaining of losing power... this against > one article on a RSR in import tuner? You do the odds.

 

JIC all the way

 

Get an Ultimate Racing 3" downpipe,test pipe,and cat-back and not worry about a thing. Total quality,Stock fitment including downpipe,no check engine light(O2 bung on test-pipe)and a great sound with a muffler that fits like stock.PLUS Darryls customer Service is there when u need it.

 

Only JDM parts are allowed on my car.

I'm heading toward HKS downpipe and 30th anniversary Hi-power catback.

 

yes I use to be that way, but 3" is key to power with a turbo car.Good luck finding this in JDM, and if You change ur mind go UR ok.happy tuning Too bad we drive Us spec Evos or u could really be JDM

 

I have and am very happy with the complete Buschur 3" turbo back with high flow cat.

It is the lightest and the loudest stainless exhaust. What more can you ask for?

 

just choose an exhaust that u like, but it has to be 3".Happy tuning

 

the downpipe comes with spacer but if youre uneasy about it,rmr sells the tie bar that clears the downpipe.
