Glasspack and rattling exhaust ?'s - Hyundai Performance Forums

BigBoi · 08-28-2003, 02:30 PM

I have read every post on glasspacks... so dont tell me to search

Problem: Buzzing, ricey sound

Setup: OBX 421 header, catco hiflow cat, 2.5" piping, resonator, Magnaflow 2.5" in/2.25" dual out(cuda body kit).

K.. so here are my questions...

1) I have no clue what kind of resonator the shop put on there... Should I just get a glasspack and have the resonator replaced? I just tried to measure it, but couldnt reach it.. but it seems to be about 18" long. If it were a louvered resonator, would this help cause the buzzing?
2) If I replace with a glasspack.. what length? on summitracing.com they have a 54" and a 28" for 2.5" in/out.
3) I am also hearing rattling which seems to be from around my cat area.. Hard for me to investigate, but anyone else had problems with rattling around this area? If so, please tell.

Thanks..
Matt

look for either a cherry bomb glass pack or a thrush magnum they both put out a deep tone to them

When I installed my obx header and left the rest stock, it seemed like the only sound I had was rattly and raspy. When I got my new exhaust, I added a resonator and the sound almost disappeared entirely. I still hear it a bit when I startup, but it goes away when everything warms up.

Well, the 54" isn't going to fit under your car.

I had that problem!!

I believe everyone w/ an obx header has had somethig like this happen to them. After I installed my header, I heard rattling and I blew out my cat. My mechanic said these are top of the line...Idon't see how you could do this. So he figured defective, so he replaced it... 5 days later, same thing. F*CK, he told me something is seriously wrong w/ my car. So for now I have a straight pipe..:ermm:
