I have one on my zilla and I like it. It fits absolutely perfect!!   Jerry did the whole motor.  But I really can't answer your question because I have not had any other pipe on that motor and don't plan on it either.  I have another zilla but I think its just a stocker with a dyno port pipe on it and it runs like a tractor compared to the built zilla.

TORQUE , the HPR puts out serious TORQUE and Usable HP! The HPR pipe will make the most significant power increase to your quad overall.
FYI also the DCS 6  and the Q-2 make good power

Leave the exhaust valve in working condition for your application

the dyno port pipe is all low end.  It doesn't even rev out anything close to the HPR pipe.   But that could have a lot to do with the engine porting also.   It is pretty obvious when you look at the 2 pipes together that the HPR is much better built.  And I think it sounds much better also.   Just the pings from the expansion chamber get the blood pumping!!!

HPR all the way.

Lots of torque over a wide RPM range and it will wind out pretty good 8K-8.5K

Just a quick question about the Hall pipe. Does it work with the front fender bracket? I assume the fender has to be trimmed for the expansion chamber but does the bracket also need to be removed? I have a new set of factory plastics and I don't want to cut the heck out of them just yet.

Yes you can run the full fender and the fender cross bar.  But you do have to trim the fenders where the pipe goes between them and the upper fender brace. I have seen a lot of really nice trim jobs out there.

Yes we are still making pipes...... I do not currently have a full time pipe builder.  We are currently working on a batch of 10 pipes but do not have a completion date.  My part time pipe builder has a full time job and I do not know how much time he can help in a given week due to his work schedule.
