HPI tuned pipe vs JP-4

[Keithv]

Ive got a JP-4 pipe on the way. I'm going to be trying it in place of my HPI tuned pipe on my LRP Z.28 spec 3. I was just wondering if anyone else has used this pipe and if so what the power and sound difference was compared to the HPI pipe. I like the power of the HPI pipe but its really loud. I'm hoping the JP-4 runs a little quieter.
Thanks

I just ordered this pipe also to go with my lrp due to some issues with the ths fitting. heard it was a good pipe. also heard the hpi pipe is not a good match for the lrp.
What gearing are you running?
