Reviews: MagnaFlow MF Series Performance Cat-Back Exhaust Systems

Very easy to install. I used car ramps on rear wheels, enough room to excess removal and install. Sounds awesome, even louder after three weeks. A very nice growl.

Install easy, and sounds great. Perfect fitment. Get a exhaust hanger tool, well worth $15-20 for no aggravation. Also wish they would have supply a new Catalytic Converter clamp.

Sounds good. Didn’t want a super loud exhaust or one that drones on the highway, this fit my needs perfectly. Just a deeper sound at low rpm

Simply amazing

The exhaust looks awesome and went together well and after the install I started it up and it sounded sweet.Well engineered and quality materials.

has a really nice deep tone to it! the guy who put it on said this ford was the best sounding ford he's ever heard!

i got this exhaust for my 18th birthday for my 2008 GMC sierra 1500 SL regular cab 2WD and i can say i'm nothing but satisfied and completely impressed. At around 2000 RPM, it gives the truck a great drone sound when accelerating but not bad when on the freeway or highway usually only when accelerating is when the drone is best heard. i noticed about 13-17 more horsepower, a tiny bit more MPG and a wicked sound when it was installed professionally by 4WP mechanics. no cons whatsoever well worth the money and a difference in power and sound is definitely noticeable

Great sound, just enough 'growl' to make me feel as tough as my truck looks!![...]

first class exhaust system

Easy to install. Sounds great!

This was fairly easy to install, but the rubber holders are a bit stubborn to remove on the stock system. After I was finished, I had a muffler shop adjust the hangers. It was a bit tight under there. It sounds mean and adds power!

Was easy to install. If you are replacing an old exhaust system do your self a favor and get a sawzall and cut the old one out. has great sound and noticed more peformance from the start.

Did not fit truck perfectly because of spare tire but shop made it fit. Great sound overall and a great buy.

This muffler system is awesome. Got great sound and awesome performance out of it. Sound is just right, muffled but noticeable throaty tone. Acceleration has increased from stand still and great passing performance. I powder coated mine black and it looks sweet behind my black H3. Stealthy yet sleeper-ish.

This exhaust was so easy to install. The sound is very mild too, just loud enough to let you know that you added it. The look of the stainless tip looks awesome.

Very easy install and great improvement in mileage from day one. sound is awesome, and look is perfect.

Love the new sound. Had a hard time getting the main joint behind the cat sealed. Had to get muffler tape and wrap the joint. Then put the factory clamp back on. No leaks now. Nice tip at the end. Not to loud. Just right.
