loud, but not too much

very easy to install. left side is harder a bit, because of the gaz tank. It took about two hours to install. The sound is normal on idle, but it comes alive at 3000 rpm. It's loud, but it isn't a lot

    Had these installed since I added cams, headers, and off-road X-pipe. I had muffler deletes and they were way too much for everyday driving. Installed these and was impressed by the fit and finish. If you do not have any other mods, these will simply sound like your stock mufflers. However, with cams or even a simple off-road mid-pipe, they sound great. My car is still loud due to the cams, but at least my neighbors can tolerate!

    All reviews are true!

    This is like having a dual mode exhaust. Quiet at idle and cruising. Above 3k and WOT the exhaust gets aggressive. I love it! Itstall was straight forward. Driver side was a little tricky, pipe was hitting cross brace, when I centered muffler. I do have off long tube headers and off road X pipe, that seems to be lower than the factory set up. Got it to clear, after I pulled it apart, wedged a pair of pliers between brace and pipe, tightened clamps down and wala! Great bang for the buck!

    Great growl

    September 21, 2012

    Best done on a lift, car must be up quite high in driveway to get the pipes in and out, but worth doing to get rid of factory crimped catback pipe.These pipes and mufflers must be used together-they have a different bend behind the axle which is not a stock copy. Procharged,cammed,headers,xpipe, my car had gotten too loud and raspy-drone prone at cruising speed with various other aftermarket performance mufflers and I was running CA special stock mufflers to kill drone (and low and top end power as well--ouch) After a computer flash-and learn tune session, the magnaflows sound awesome- low and growly at idle- rumble but not drone at 1.5k to 2k hwy cruise and not much louder untill top end/WOT. Good flow, I am not plugged up on low and top end power with these They can be heard at all speeds with top up or down, but I can also hear the shaker stereo if I turn it up some.

    Great bang for your buck. I didn't know what to expect when I ordered this and put it on. Installation was very easy only using a few wrenches. Installation time only took about an hour. It was quiet at first but after some driving it does get louder and the quality of the sound is great.

    loud, but not too much

    July 05, 2012

    very easy to install. left side is harder a bit, because of the gaz tank. It took about two hours to install. The sound is normal on idle, but it comes alive at 3000 rpm. It's loud, but it isn't a lot agressive. I recommend it to people who would like louder sound than the original one, but doesn't want to have exagerate sound.
