We put the HMF on my brother in laws then rejeted. You can not hear yourself think it is that loud. The low end power is gone!! Mid and top is good. No mater what I did to the jeting it would not get the low end back. Now the Big gun works on them and not real loud.

 

Thanks BigRedRinny I think I will go with the MBRP Powertech thanks for the help.

 

HMF is best for the most power gain possible at this time with an aftermarket pipe for the Rincon. The MBRP is nothing close to sounding stock. I have heard them and they are PLENTY loud, just not as loud as the HMF. They both sound really good and both have good qualities to them. Evidently there is a Supertrapp out now too. Diamond G Racing has a stainless system that comes straight out the back, they say it has a tone similar to the MBRP. Pro Circuit ang Big Gun also have exhaust systems for the Rincon for sale right now.
