Thunder Monsters
Well here's the deal from Big City Thunder on HK 3" big Straights::::
Due to the design of the Hard Krome baffle you would need
to do one of the following to use our products.
1. Make an adaptor. We can send you a CAD drawing.
2. Cut out the baffle that is inside your Hard Krome pipes
now, leaving the outer carrier piece intact. You can then
install a set of Thunder Monstters in the original piece.
3. Order a Straight Thru Baffle from Hard Krome and
install a set of Thunder Monsters in them.
I dont know if they are worth the effort at this point. ??......
