Which is a better slip on pipe? The Pro Circuit T-4 or the White Brothers E-Series?

 

The E-series is a good power gain, but the product quality is junk. I have 2 in my garage, and they have been repaired 5 times total, with one broken right now.

 

I diagree with you becuase i have had only one whitebros e-series pipe and same with all my riding group we have never had any problem with them tehy never broke or anything

Well with white bros e-series do u want s bend or pro mag if u want better power go with pro mag but if its to much money jstu go with a s bend they still give great power

I have seen improvement on them over time, so maybe they finally fixed them. I was just giving my experiences.

 

I had a PC T4 on my 400EX and had no complaints. It sounded good and had great power. The only pipe I would take over it is an HMF.
