IMHO if you want Power but not a loud exhaust there is only 1 choice... HMF Swamp Series!
Most comments I have seen about the QS1 is that it is still pretty loud, again definition of loud varies person to person.928GT,
I looked over at Highlifter for the HMF Swamp Series, but at $399.00 it's a little hard to swallow. I can appreciate the technology used and not needing to rebuild, but is it really worth it if I'm not playing submarine?
I've been looking at the Performance Kit over at ATV Outfitters and for $350.00 I can get a HMF QS1 Eco System, K&N Filter, and a jet kit. I DO want to add a little "sound", I just don't want to piss off the wife and I wanted to get some opinions before I wear out my keyboard.
