"This was a very good purchase for Si. I didn't want a loud "ricer" sound. I wanted some gains in power with a good deep low tone. This exhaust was perfect. I noticed good gains and a great tone that wasn't to loud. The value for the money on the magnaflow was great. I had a shop install the kit and they said it didn't bolt up really well but they we able to make it work pretty easily. I wouldn't have been able to do it. They also welded the parts together instead of bolting them, I would recommend doing this in installation." —Brock M from Gaffney, SC bought a Magnaflow Exhaust Systems for a 2004 Acura RSX.
