I Cant stand the rasp but love the responsiveness that the test pipes give me has anybody every just added a resonator into the stock y pipe? Did the fix the rasp problem? I'd like to keep the pipes on but the rasp has to go away otherwise the test pipes are going. Advice or other solutions?

 

Motordyne XYZ pipe with resonater should fix your problem

 

I would suggest adding a resonator to an aftermarket y pipe or purchase one that already includes it

 

I guess I should have just purchased resonated test pipes in the first place. I sadly with a new house don't have alot of cash laying around. So I am looking for a fix to this problem that dosn't cost me an arm and a leg. What do you see as the cons of adding a test pipe into the stock y pipe? I looked at aftermarket y pipes and most seem like they wouldn't lend themselves to being modified for a resonator.
From what I am hearing the resonator will eliminate that awful rasp.

 

Resonated TP don't work as good as a good resonator later down the exhaust. I've had both setups. Best is 2 resonators on each part of the Y pipe, or a big resonator down the midpipe.

 

Yeah Im going to buy this http://www.summitracing.com/parts/SLE-31066/ and slap it in and see if that kills the rasp.

 

Let me know how it works out for you man, am getting mine put on next week and i imagine since i bought the stillen Y pipe it my cause some rasp as well. I felt a bit when i installed the headers so hopefully if it works for you it might work for me.

 

Update:
Havent been able to work on the Z and had some things come up at the house that needed to be addressed.
Anyways I got an answer from dynomax and they suggest using this http://www.summitracing.com/parts/WLK-24222/ its alot cheaper and is a muffler not a resonator.
My Question is:
is the SLP worth double the price. I really dont want to have the rasp and I want to ensure I solve the problem , and I certinaly do not want to slow my flow.
lets hear it!

 

Go with the DYNOMAX, there shouldn't be any difference from either one.
