I'm pretty much saying exactly what I.B. Hoggin said. I think that "y" ing into a collector and a single pipe through a single muffler with a single tail pipe both defeats the purpose of the fentons AND might just make your truck sound like a tuner. I would like to hear it though - just to know!!! BTW The shop that did mine had it done in less than 3 hours and charged me $300.00 for 2" duals from the fentons and out the back. As you know, I provided the "dual in, dual out" muffler from Patricks.
