Hey guys, jus installed agency power single, stillen y pipe and top speed test pipes. There is a buzzing noise when you let off the gas, is this jus rasp or something else?. I heard once that new exhaust my sound like **** for a while.

EDIT

So last night someone told me I have an exhaust leak. Its not rasp. He covered my muffler with one hand and told me to walk around the sides of the car. Its a leak on the left side that's where the noise is coming from. Am guessing my y pipe or left test pipe isn't on properly. When driving I only hear it on the left side I forgot to mention that earlier. Apart from that this exhaust set up is beast not for the faint of heart extremely loud and aggressive.

 

anyone? should I jus get a resonated y pipe. Would that reduce my gains.

 

I could be making contact with an underside brace off throttle. My Tanabe exhaust did this.

 

my money is its just crazy rasp. I installed my Trial titanium exhaust just recently and it sounded excellent with the cats, the moment i installed test pipes the rasp became so ridiculous I thought it was something touching something else and spent hours rechecking everything removing heat shields/checking the gaskets/ removing/reinstalling the test pipes and checking/adjusting clearances. So yea....probably just rasp form the titanium muffler. Try throwing the cats back in.

 

Ahh I see. Thanks for your replies guys. I will be double checking everything. Removing the test pipes on an hr is something I never want to have to do again lol. Here is a short vid i took. Listen the sound the exhaust makes about 3 seconds into the vid you will hear it.

 

haha, you need to change the video to public instead of private

 

lol damn, I uploaded it using my phone I will try and fix it.

 

It should be working now

 

to me it sounds like resonance/back pressure in the test pipes. when i first installed my art pipes i noticed a rushing type sound for a bit....

 

Oh I see. The thing is that bmurray has the same set up and he doesn't get that loud buzzing sound. "For a bit" So it went away after awhile?

 

or i just dont notice it anymore

 

Yea probably

 

i have the same exact noise now with my art pipes. except mines between 1.5k and 2k rpm. and it also happens when i let off the throttle. but my art pipes make many noises so i dont really worry about it.

 

Mine happens anywhere in the rev range below maybe 3k rpm. I thought art pipes were suppose to get rid of things like that

 

the resonator on the motordyne ypipe does get rid of all kinds of rasp...art pipes not so much...

Oh ok thanks for the info. I will look into it if I ever need to get rid of rasp or quiet down the system. It doesn't rob performance though right
