More growl, more horsepower, and hopefully better MPG!

I recently had my Heartthrob exhaust system installed on 2005 Chevy Silverado 2500 HD with a 6.0 liter 8 cylinder engine. The first thing that I noticed when I cranked up my truck was a definite growl as it roared to life. I was worried about excessive noise inside the cab of my truck, but once I reached crusing speed of 60 mph it was just a nice bass hum: also crusing at 60 mph my tachometer was showing 2,000 rpms, with my old system at 60 mph my tachometer would be showing 2,500 rpms.

Great price, sounds great, looks great and I definitely have more pickup on the highway. I combined it with K&N cold air intake. Only problem was had to cut about 6 inches off just before muffler to get hanger on pipe to line up with hanger flange on truck. Also had to cut about 3-4 inches off the 90 deg tailpipe cause it stuck out past fender well. Was expecting it to line up without cutting. Overall its a great buy!
