The sound quality of this exhaust is excellent, it really wakes the Hemi up! The hardest part about the installation is removing the stock exhaust but other then that installation is pie even if you have zero mechanical skills. Just have a buddy help you out and putting the new exhaust up should take 45min to an hour. Great exhaust tho I'll definitely be purchasing another one from autoanything when this truck is done

Very easy to install motor runs better better gas milage. It really woke up the beast in the 5.7hemi. Recommend this for every DODGE.

The diagram was super simple to follow. All the supports lined up like Flowmaster knew what they were doing. The price couldve been lower but then again autoanything was the cheapest place I found the kit, and you can't beat free shipping. They gave me the powerful tone I was looking for. I simply love my nerw exhaust.

Excelent!

This system sounds great when you get on the gas! This gives the Hemi a mean roar! Others complain about the drone from the MDS, but you don't really hear that unless you have it dumped under the bed. The only way I know that is the right side clamp came undone after it was installed, so I recommend having it welded.

I am extremely satisfied with my purchase of the 50 series muffler and pipes. Sound is incredible...finally my Hemi sounds like a Hemi! Price is very reasonable too. The only thing I would suggest to improve would be larger chrome tips. I didn't use the ones that came with the kit. All in all.....Buy it! You won't regret it!!!

I installed it on a 2008 dodge ram with the 5.7 hemi, Installation was very easy, took me 1 1/2 hours to remove the old one and install the new one and I have no mechanical skills what so ever, looks and sound great but my gas mileage went down like 2 miles per gallon. power gain not really noticeable.

The best modification on my truck to date!

The sound of the 5.7L Hemi was incredible. I got the dual rear exit exhaust and just the look of the exhaust system from the back of the truck made it look fast. The quality of the exhaust system is exceptional. I do suggest however, that owners tack-weld the exhaust pipes. Horsepower gain was noticeable as was fuel mileage (if you drive it conservatively). Overall, I'm very impressed with the quality and performsnce of my Flowmaster American Thunder exhaust system.

Sounds GREAT with the HEMI

Great product! Big improvement on the stock system. Worth the money. I had a little trouble getting the dual exhaust level but that was purely a cosmetic issue. The clamp are little tough to tighten down but with an extension on the ratchet it tightens much easier.
