Internal exhaust mod

I agree the FVD probably sounds the best, but it is very pricey. The mod Particlewave and I did will get you 90% of the FVD sound for almost free. I guess if you took it to a shop it would cost you at most $200.
My buddy sent his muffler to Fister to do the external mod. With shipping back and forth I think it was close to $1000. The internal mod sounds almost exactly the same as the Fister mod, but way cheaper and no extra pipes visible.
