Also how is the power increase? I read in a youtube comment one guy said it was up to 155 at the crank? that seems like an awful lot to me

 

ViperRaceCans on 2 of mine ( 90 & 93 ) - a nice roar under heavy throttle -
( does not attract the law ) under moderate throttle..... nice drone when cruising,
Matching elbowed baffle inserts for annual inspection.

 

I thought they were in stock when I posted the link, some people may have seen it and jumped on the deal.

As for power I'm not sure, still gotta replace the gears in my tranny and then I'm plan on putting it on a dyno to see what she's doing.

Have you checked ebay? I know I've seen the v&h systems on there a couple times so it may not hurt to look
