    Comments about Dynomax Ultra-Flo Welded Mufflers:

    The mufflers sound great. I put these on an 2007 Maxima and so I wanted something that complimented the car and help give it that deep Infinity growl. I irdered the wrong size and had to exchange them, but other than that it was great. I am going to have my resonators cut off to help it be a little louder. Surprisingly it is not that loud, my cold air intake is louder than the exhaust. I couldn't find anyone who had put this on a foreign car so here's my feed back. A nice low end clean sounding growl, not a bunch of angry bee's.
