Definitely sound, throttle response and passing power gain, a little better gas mileage.

This is one of the best upgrades I've made on any vehicle. The sound is awesome. It doesn't have the same muscle sound Flowmaster puts out, but it is very deep and powerful sounding. The quality of the muffler way outdoes Flowmaster. Sounds more like a Corvette or Viper than a muscle car. At WOT it sounds great. Very performance sounding. I could feel the h.p. and torqe gain from the begining. Bought a Borla tip at same time and it is beautiful on my suv.

Looks Sound Quality

None so far

Bought the universal muffler and had it installed at Muffler Man. 4G civics go thru mufflers like its going out of style but this one (stainless )is holding up really well. Nice smooth tone. Did notice increase in mid range when partnered with intake. Not too loud. Recommended.

The sound is incredible. I originally had a DynoMax Super Turbo muffler but I wanted a stainless-steel muffler and also wanted to increase my piping. The quality is top-notch, the sound can't be beat and it makes my car roar!

I paid $131 for my universal Borla Hemi muffler and then took it to a muffler shop to custom make the 2.5" piping. Overall, the total cost of the muffler and installation was about $210. I recommend it to anyone and everyone with any type of car. I installed it on an Accord and it just makes my car scream with a nice, deep rumble at idle and a VERY, VERY bassy tone when accelerating. It makes my car sound muscular and is better than those stupid riceboy/motorcycle-sound/farting-on-the-toilet/bee-buzzing mufflers all those other import guys use.
