HMF or Procircuit T-4

[400exr]

I'm trying to decide between the HMF slipon and the procircuit T-4 slipon. I can get them both for exactly the same price, so all I need to know is which ones the better of the two? If it helps any I'm going to run a K&N and some holes in the lid. I gound down the header pipe welds too.

I'd def. say the T4.....awsome lowend gains!:D

The T-4! Great low-mid power gains.:devil:

I have the HMF and like it. Good gains. But I think you will find this site split between t-4 and hmf.

i love mine sounds good and everythingplus sweet power gains over stock

T-4 all the way:devil:

i would say hmf but really neither, the wb slip on has more gains, the e-series also the ct racing slipon has more, but if you want alot of bottm get a tc racing pipe

Sorry man, across the usable power band the WB is not better than the HMF... at least not when I compared them back to back... I got the HMF... sounds better too :p
