Hey guys for anyone who has this greddy exhaust, i have only had this on about 4 months and a bad rattle has developed. I took a look at it and felt an exhaust leak between the resonator. There are no clearance issues either. No heatshields are hitting it and its driving me nuts. i went to 2 different shops to get it checked and they say its the resonator. but the shop that i got it from say it could be my catalytic converter. but if it was that im sure my 95 civic will throw a check engine light on. i can't figure it out what but have concluded that the baffles inside the resonator were coming apart or loose which was causing the rattling noise.

Well heres the thing the shop say that greddy has a 3 yr warranty which they say they will take care of but the thing is i have to prove that it is the resonator problem and not the cat.

Anyone have any suggestions?
