was louder than I liked so I replaced the muffler with a GM product which reduced down the load tone. overall I had a pickup of speed which was a plus.

I purchased the single side swept system about a month ago, I purchased this with the Black Metal Mulisha tip put the system on my h3 as soon as it arrived, installation was pretty easy but I recommended having an extra set of hands I installed it on my own took me about 3 hrs, removing the oem system was the hardest part, as for sound its not too loud but it gives it a nice aggressive exhaust note and dont worry it sounds nice, I was a bit worried that it would sound like a Honda Civic ......
