Reviews: DynoMax Ultra Flo Cat-Back Exhaust Systems

Worked great on my 2008 Jeep Liberty KK. Hardest part of the job was removing my old exhaust and wiggling the new one through into position. But as long as you know how to use a reciprocating saw and some wrenches than this will be an easy job. I'm pleased with the sound. I wanted something just a little louder and "better" than the stock. This is just that, a little bit of growl but not obnoxious. I wouldn't mind it being just slightly louder but overall I'm happy.

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

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!

The quality is very high. Stainless steel components with band-type clamps for easy installation, adjustment, and removal. It sounds real nice. Not too loud and no droning. I gained about 1.5 MPG average on highway driving.

I went through a GIbson dual exhaust and a Ruged Ridge dual. Gibson was toooo loud inside with hardtop on and broke off at the hanger after 7 months of mild highway driving. The Ruged Ridge was softer but also broke at the weld and eventually fell off after 5 months. The Dynomax was much harder to install a lift and a garage is Recommended but it sounds great and power is also there. This one seems much Stronger.

Better than OEM on fit, finish and materials. PLUS- it was cheaper than a stock replacement system!

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

Great bang for the buck. This is a great sounding exhaust, not too loud/not too soft. Nice looking chrome tip. No drone on the highway.

Very nicely built. Goes on super easy. It took me less than an hour to get the old one off and new one on! Has a great sound but a little bit synthetic for my personal taste. I think it is great for most but I have 2 small kids so I called Dynomax and they sent me the Super Turbo and it is much more to my liking.

Added the dual exhaust with the cold air intake and to increase fuel efficiency. Also got a great sound and a little more power.

Put this system on my 4wd silverado, very cost effective, especially with the rebate offer.Quality components, easy to install, the only negative comment would be the universal type rear u bolt clamps and hangers. Should of put the oem type hanger welded to pipe, you can see the clamps from the rear, so it is not as clean as it could be. Sound is nice, not too loud, good product and is even stainless.

This exhaust system was easy to install. It took me 1.5 hours useing simple hand tools. I have not driven it long enough to tell if it will improve the trucks performance or fuel milage. The only negative I have for the system is that it is a bit noisy in the cab at hard throttle.
