This our "go big or go home" style of sidepipe. The Give No Mercy! (GNM) HighFlo Performance 2.5" inner baffle stainless c2 sidepipe mufflers with 304 stainless tips. If you don't like your neighbors, you need a set of these! We take great pride in manufacturing everything in our shop in Michigan from sidepipes, mufflers, and full chambered systems for early to late muscle cars. We use these for making all of our loud talking c2 sidepipes for small and big block. These are our complete jig fitted systems for c2 corvettes and we pride ourselves for being the only company with the true original inner baffle for the c2 corvettes supplying all the NCRS cars built. These have a 3" outer casing which is the largest that you can correctly fit under the factory C2 covers. So throw out your worn out, blown out mufflers and pick up a new set of HighFlo Performance sidepipes today!
