Resonated Test Pipe Help
 

I know this has been discussed before and I have done some searching on it, but can't seem to find a definitive answer. The question is, "How much of the rasp/rattle do Resonated Test Pipes eliminate as compaired to Straight Test Pipes?" Also, which brands do a better job of it? I've been looking at Meagan and ERZ.
I have the SureWin Y pipe and Top Speed CBE to go with the RTP's.

I need this question answered too...help please! To add to the list above, I'm looking at the Fast Intentions resonated test pipes/straight pipes...

I have your set up - I ran non resonated TP's and I did it for one day only.

I have ran resonated TP's and it was better but there was still rasp.

The only time I have never had some sort of raspy tinny fart was with the following.

TP's with Invidia Gemini
ART pipes with stock exhaust
HFC with stock exhuast
Stock cats with surewin and TSCBE

If I were you I would get some ART pipes
