Bump

 

I think the E-series is JUNK!

 

Of those three I would get HMF. That is the pipe I put on the 450 when the time gets here.

 

Anyone else?

 

Hey Sick, out of the three you chose, they would all do fine but the HMF is louder and the E series does have weak mounts. I haven't heard too many complaints about the PC T4. I really like mine!

 

Anyone else?

 

I think the main reason the white bros e-series welds break is because they are so long that when you hit your grab bar when riding a wheelie the end of the silencer hits the ground. I'm not sure if the HMF or pro curcuit is any shorter but they would prolly both definatly break if you hit the pipe on the ground with all that force. Any way you chose you really can't go wrong. The E-series has a disc system which is nice because it is easy to quiet it down if you ride where there is DB limits or your if neighbors get pissed off, and it can also be opened up more if you race and need the extra power.

 

Hello

 

get the e series you seem to have your heart set on it.

 

hmf has a quiet core insert for 20$ that brings it down to 92-94db, they say it doesnt take away any noticable power either and it comes with a free spark arrestor, that you have to request when ordering. so even with that extra 20$ the hmf is still cheaper than than the PC
