Hardest part was getting the factory exhaust off my '06. Has a good sound, definitely not too loud- nice and low and the best part of this exhaust is getting on the gas a little bit. Helped with performance and maybe a tiny bit of mpg. No drone at all. A bit overpriced I would say, but hoping it lasts a long time.

Went very well once you get old system off, I had to cut it out. The only thing is you buy a really nice exhaust system & you have to use your old bolts to attach. Which for me snapped off when I took the old one off so I had to go out anyway & get new bolts. Very pleased w/ it, performance is better but I still have OE manifold & cats so I'll really see wut happens w/ my new OTTP header and only one high flow cat.

love it

Great product,Fast Shipping.I also ordered the magnaflow cat along with the exhaust and it definitely has made a big difference.Had to run to the hardware store to pick up two nuts and washers that were not included and didn't come with new nuts where the cat bolts up to the header mechanic had to bend and tweek the hangers on the tailpipe section a little bit to give the pipes plenty of clearance from hitting the frame crossmember.wouldnt suggest putting on yourself.other than that i would definitely suggest this muffler to anyone.

Fast shipping, great price and easy to install. Everything fit fine and at idle it is hard to tell it has the exhaust on the truck. Step on it and you feel the difference. I have not checked the mileage yet but with my foot in it the mileage will not be good.

Nice sound not much in added performance

Installed on 2007 Chevy colorado. Good quality kit, nice sound (not loud), easy to install. More work removing old exhaust. Slight improvement in mid to high rpm power, no increase in mileage. Received more power and better mileage with cold air intake kit at half the cost. Tony from NOCAL

High quality,fit perfectly,muffler shop had it installed on my 05 Chevy Colorado Z71 in less then 15 min. Combined with an AirAid intake system with their PowerAid throttle body spacer,my truck now feels like it has a small V-8 in it.Very noticable increase in power and torque in the low and mid range.Inside the truck the sound isn't any louder then stock,even at highway speeds,unless you really put your foot into it.And the large polished tip makes it known that you've got something under your vehicle.It looks great.And dealing with AutoAnything couldn't be any better or easyer.

Nice sound

The magnaflow catback system makes my truck sound likes its just eaten its wheates. It's not crazy loud either so the police don't give me that crazy look when I pass by. Great product and that discount made it even better. AutoAnything is the best!!!
