dont like it what so ever. but i have n choice. my cat was all busted up inside holding up way too much backpressure causing the bolts to loosen and fall on the freeway, next thing you know, i was on open header draggin my exhaust.

but id get a cat. OEM if you can get one. the aftermarket once the muffler shop sells are booty. besides the magnaflow high flow cat.

but yeah oh btw, i have N/A SR20DE.

I'll stop saying it's ok to do i guess I was outnumbered. I really just didn't notice any difference in sound or pick-up soooo I just figured that it was a great alternative to replacing more $$$ parts?

wow, you guys were just made for eachother.

100-200 bucks is a drop in the bucket for a high flow. man up, pusscakes
