hi i have a 97 GS-R with jdm type-r headers an DC Sports cat-back an i had a jdm cat but that **** the bead an i put a mangflow cat on it but i dont really care for it i notice some what of a decresse in power very little but every bit helps lol so i was woundering if i could put a straght pip aka test pipe on there an run an o2 simulater to prevent my check eng. light form coming on is this a good idear or bad one. what are the pos. an neg. thanks is there a easyer way of doning this RIGHT with out gettoing it an throwing a light lolol thanks for any Help

 

First, search.
Second, do it the right way and get a better flowing converter from a place like SMSP. Look them up. "Test pipes" are illegal in all 50 states as an FYI.

 

I agree with Wraith_G2IC, contact SMSP and tell him your setup and that yoy need a high flow cat, and he will fab one up for you.

i have a high flow cat... works wonders... or you can just gut your cat that you have on. and if you get pulled over, just act like theres nothing wrong with your cat

i live in ohio too... cleveland. i got my car inspected

where are you from? are you on ohiohondas.com?

 

It's not a "state law" guys, it is a Federal EPA law. Just because you don't have a state inspection doesn't mean you get a "free pass" to do whatever.

 

go on ebay and get a cheap test pipe....thats wat i did....saw a gain of 5.2hp dyno proven... passed my emissions with flying colors....an i didnt change the sound of my stock type r exhuast

Get a cop in a bad mood who smells your eye-watering exhaust and they will do a field inspection and administer a hefty fine.

 

yeah iam iam but i dont find much use for the site lol just yet lol but yeah iam form lima i go to northweastern ohio but iam form Boston iam just here for school

 

do you have to have your car E-checked where you are in Ohio ? if so you can do what i do seeing as though they just look to see if oyu have a cat. i just took a big *** screwdriver, and knocked all that **** out of the cat with a hammer. hahaha
works well.

 

i've seen dyno tests where a test pipe made like one extra hp over a high flow cat on a built motor. u might as well get a cat. u stay legal and theres not much of an increase in noise. like was already posted, check out smsp's site, he sells some high flow cats. u will be happier in the end.

 

I say test pipe all year round until you have to get emissions then you throw the cat back on if you get a ticket its always just a "fix it" ticket and thats easy to take care of.

 

ooo a fellow clevelander... where you from? i might have seen you around and given you thumbs up before lol....

but yeah, as stated before, its safer just to go with a high flow cat.

 

Well I have a 3 inch resonator welded into my exhaust system without a cat. 3 inches all the way. it can be loud but since i have a turbo on it it's quieter than if u ran it with some 4-1 headers. O what the hell, get a resonator with no cat. get the 02 bunged in their somewhere and ride like crazy. lol

 

im about 25 min. west of cleveland, dont take my car downtown to much anymore...

west 6th is fun to be on when its nice though. haha

 

just gut your cat like i did. It doesnt make a noise difference with a turbo setup. Better flow, i notice the difference of sound and power.

 

hollow out your cat and put it back on.... thats what i did.


after the 100 octane melted it . made it a whole lot easier to hollow out though
