Packaged very good, pretty easy install, and sounds darn good.
Loved it really easy to install and sounds great just wish it had better looking hangers can see 2 of them fron the rear and they don't look so great
Better than OEM on fit, finish and materials. PLUS- it was cheaper than a stock replacement system!
This was the easiest install I have ever done & it sounds great
I was excited about the addition of this exhaust system. It completed my performance upgrades and now my F150 sounds great going down the road.
NO DRONE in 4-cylinder operation! ('09-'10 Chevy/GMC 5.3 V8). Plenty of RUMBLE.
GREAT price on an excellent exhaust. Why pay twice as much on others? I'm VERY happy with this system, looks great, easy to install and sounds fantastic. And it really opened up the midrange on my 06 Tacoma with the 4.0 V6. Two thumbs up!
Installed on my 2010 4.8 gmc. Love the sound but it is a little too loud in the cab. Dynomax is sending a new muffler because they think the packing went
