What pipe should I get?

DMC or Big Gun or do u guys have another pipe that u think is better.
Thanks, matt

 

I run the same mods as you do but I installed a Supertrapp IDS2 and I'm very satisfied. I used to have the FMF Powercore IV but it's so loud. I used the 18 discs that came with the pipe and it pulls better from low to top end as against the FMF.

 

I went from a Big Gun to a DMC (Accident) And there is definatly a diffrence especially in the upper third of the RPM range. My setup is close to yours i only run a 426 though. I have beaten a 440ex up sand mountain the only diffrence between the two was my carb and our pipes, he had a e-series. He was impressed.
