im putting a hi flow cat in my car real soon, question is, will the car be annoyingly/illegally loud ?? or just a nice quiet deep tone ? right now i got a stock muffler but probably within a few month after the no cat replacement im going to put a muffler..

 

It won't be noticably louder.

 

well depends on what exhaust you get on my greddy evo 2 exhaust 2.5'' system i had a stock cat then i punched the cat threw and it was a little louder o and no cat or straight threw cat will smell badddddd the gases are horrible depends where you live to matter how loud it can be i live in nc and cops dont care about how loud exhaust is i used to run open header in my civic and pass by cops, in cali you wud get ur *** pulled over i remeber those days in cali but that isnt y i moved to nc if u live in cali ur screwed id get pulled over for just driven a honda or low or hear vtec pop or exhaust
