Hey guys, I bought a used Pro Curcuit T-4 pipe today for my 400ex. I paid $150.00 for it. It had one little scratch on it. I got the scratch to come out with some steel wool and some Mother's car polish. Did I get a deal? The guy I bought it from owned the local quad shop. He said it was only on the quad four 3 weeks. It was on his son's 400ex and i guess he wanted a different pipe. Also, has anyone out there played with the tuning of this pipe. Which end caps work the best for topend gains, and for lowend gains.

Any answers will help

Thanks, PhatDaddy

 

The guy i bought my quad off of had tryed all the endcaps and the quietcore and he said the largest endcap is your best bet all around and the quiet core is a waste of money. As a rule of thumb though, the smaller endcap is better for bottom end, the mid sized for midrange and the larger for topend.
