I have a set that have are silver powder hot coated. Mufflers have already been replaced with the 4 OD, 3 inch ID straight through bullets. They are loud, but zero loss of horsepower as tested on the Dyno. The bullets were welded in and the weld job is not the greatest. Furthermore, one of the primaires on the passenger side has a dent on the bottom from where it hit a rock. The hot coat will clean up great, just needs a little polishing. If you are interested, email me at
c.croshaw@att.net and I will email pics to you by Friday morning (currently out of town).
