Replaced the blown out flowmasters with Mac flow path. 2-1/2" inlet, and around the same size casing as the flowmaster 40 series. This is on my Jeep Wrangler and I'm finishing up the flanges to weld everything back up. Cannot wait to hear it on the streets!!!! These took about 2 months as they appear to be built in small batches.....but defiantly quality!!!!!!
