i want something that adds a lot of low end grunt I also want something that i dont have any packing to replace

 

Me too, but needs to be quiet

 

I agree

 

ok i know the guys are probably going to nag on me for saying this ... BUT ... FMF is known to be quiet and you should try their utility exhaust line.

 

actually no I have been looking at the powerline does anyone have one

 

I was told the FMF's are quiet but not much gain from their silencer's. Might be true might not just what I was told. If the power gain is there I would jump at one.

 

I have the Big gun utility on my 400. its legal guaranteed at 96db or lower but it isnt quiet. it added some low end but I blew some packing out on my last ride, they claim you never have to repack...not true

 

White Brothers E-Series with 12 discs in it will give you some major low end torque. Add the quiet core insert to make it 5-6 dbs quieter!

 

I had an E-series on a HSP header. that e-series just fell apart on me. not to mention it was loud, very loud. with 12 discs you will have little low end power, and the more discs you're running the louder it is. I usually ran 5-7 discs and it had great low end grunt. I had a quiet core but the welds broke and it just made it sound like crap. its just pretty much a couple pieces of scrap metal welded together
