ive had a Walker/Dynomax catback bolted to a Bonez cat-replacement pipe for a couple years and i think it sounded great. fairly deep, even at high rpm, no buzzing whatsoever.
i just put in a RB streetable header w/ presilencer, same catback. exhaust note is a tad bit louder, not as much as i expected, and sounds good at idle and low rpm. but all im getting above 3k rpm is pure buzz. cant even hear anyhting that resembles an engine sound... wtf. the catback sounded so good with a stock ex. manifold...
since i cant stand the sound, i want new mufflers. anyone have sound clips, or at least opinions on some dual muffler setups w/ RB header/presilencer? im thinking magnaflows, as they seem to sound good on anyhting else, or Apexi N1s. (i dont want a full system, just replace the mufflers).
i hate this damn buzzing!!! its seriously pissing me off. the car sounds so much worse than all these CRX's around here with ebay fart cans. its rediculous.

 

I thik that the bonez superflow catalytic convertor and there catback exhaust should solve your problem.
What do you think

 

Sounds like an exhaust leak. Mine does that. I've got a Factory exhaust I kinda lazily put together and it buzzes at about 3k as well.

 

you might have a messed up exhuast gasket somwhere... good luck with it

 

Apexi' will only add to that buzz for a muffler, if you want a quiet one Racing Beat or a selected Magnaflow would do the trick. Whats wrong with the dynomax ones?

 

My dynomax on my first gen sounded pretty beefy.

 

my full racing beat sounds bad ***
no buzz... maybe you need to re-torque your header? did you use the old gaskets (bad) or new ones (good)?

 

My full RB RoadRace system sounds Great & looks AWESOME!

the buzzing is definately coming from the back of the car. i sat under the car listenening for exhaust leaks- as far as i can tell everything is good and sealed (all new gaskets too). the only noise is coming from the tips. im thinking maybe the dynomax mufflers burned out or somehting, and have loose stuff in em vibrating at higher rpm. the buzzing starts right about 3k and continues to redline.
im looking into getting magnaflow strait throughs (7" thick, 14" long can, 2.25" in/out)
aside from RB catback (im trying to save money), what else out there does not have the rice buzz when combined with the RB header/presilencer? i just want mufflers i can weld on to the existing pipes.
-its so hard to find vids/audio of barely modded N/A's...
