I have Berk-HFC, but I haven't install it yet. I going to get topspeed pro-1 dual exhaust 76mm soon, and I want get a y-pipe. Any suggestions of y-pipe brand for a deep tone and preformance or anyone has that setup of (Berk-hfc, y-pipe, and topspeed pro-1 dual exhaust) and tell me what your experience of the setup?

 

There is really only one worth buying

 

^ motordyne

i really wouldnt waste money anywhere else

 

It's a y-pipe. It's not rocket science. Find one you can afford and buy it. No one's exhaust tubing is any more special than the other. Make sure it's mandrel bent with flex joints and move on. I'll get flamed and told I'm wrong but oh well. I'm not wasting money on freaking exhaust tubing because one guys tube gets 1hp more than the other or "sounds" better than the other. $20 on a blind test no one could tell the difference between motordyne and one bent up by a local exhaust shop.

 

Location of the merge point and the collector for the merge point make a difference. Then you have tubing quality, flange quality and a few other things to factor in.

 

tony colette from motordyne would completely disagree with you, as he IS/WAS a rocket scientist

 

Agree that there are some inherent design factors that differentiate Motordyne (I run several of their parts), but having seen several Motordyne exhaust components, they are far from the paradigm of precision. ^After all, rocket scientist or not, Tony and the company still need to...drum roll please...make margins, make money. Good customer service goes a very, very long way.
