you can also go with a test pipe with a o2 sim.

o sorry. i forgot about that. here in NV i think everyone and anyone with a modified exhaust has a test pipe. lifted trucks/hondas/nissans etc.

[nho93accord]

it'll help. but DEQ might fail you, like a 50-50 situation

He would not need a o2 sim since obd1 cars do not have a secondary o2 sensor

i have a test pipe... it illegal in vancouver as well but whatever, until the day the cop gets on his knees to check. But im running it with a GReddy Evo II cat back and the only reason i got it was because it was $30... but i have to put my old exhaust back on or at least the cat for AirCare.

If you plan on getting a cat-back system then go for it, but if your using the stock piping it won't make much of a difference, really... but then again if the price is right, whatever just do it!!!!

another option is, if it illegal where you live is to take a stock cat and hollow it out with a baseball bat, that way you get the benefits and not the ticket

[SwiftCB7]

if your gonna get a high flow cat... get larger pipes also it will be worth it... also you wont have to do it in the future

Just be a savage and get strait back piping...best way to go...or if your worried about inspections just hollow one out...

don't you get dizzy when you breath in the fumes? i took mine off b/c of that.

Hollowing out your cat will actually make you LOSE power.




High flow catalytic converters are not worth the price. Just get a quality replacement and you'll be fine. If you want to do it anyway, get one from SMSP or MetalCat.


There are better things to spend your money on.
