and i dont want to hear any of this crap about sweet-thunder or stainless works. they have 3", but the cores are still 2.5" at most. wtf? i dont want fiberglass packing! i dont want a true-dual loudmouth! im looking for a "homemade custom true dual gmmg" which requires chambers, not fiberglass packing like the dynomax bullets.

btw, sweet thunder or stainless works wont respond to my emails.

last, how much hp can a dual 2.5" system support? if i cant go LT>X>3"s, ill go with dual 2.5" sweet thunders. but how much hp will i compromise if i go dual 2.5" instead of dual 3" (like, bullets)

I believe 2.5 is good to beyond 500 rwhp.

good god!
chambered it is!
does anyone know where GMMG gets their chambered pipes from?

if not, i guess its down to sweet thunder or stainless works. any suggestions, guys?

I have the Sweet Thunder 2.5" Chambered stainless steel mufflers and they are very nice. I think they are cheaper than Stainless works also.

fwiw you can get dynomax straight thru bullet mufflers that are 3"ID for like $35 at jegs or summit.

Summit Racing has some stainless chambered mufflers. They're pricey though.

I think Patriot makes some too.
