Guest Anonymous Posted October 16, 2001 Share Posted October 16, 2001 thanks for the reply, is that a whole system i can order? if so about how much did you pay? is it better to have a system custom made? Quote Link to comment Share on other sites More sharing options...
DavyZ Posted October 16, 2001 Share Posted October 16, 2001 Ken, you might want to consider two mufflers in line to get the sound down to a reasonable level without harming performance. Some guys that have a resonator first in line and then a muffler still complain about a droning noise at speed. From my reading, it seems that the guys that have used an actual muffler, even if it is a straight through design (for the first in line) and then a larger muffler at the back end of the car, have significantly cut the noise and have no/little droning. I bought my system used from a guy on the board with his assurance that it was a "quiet" system. (it is not hooked up yet, so time will tell, but the quality of the system tells me it is for real) The system is a single 3" mandrel bent system which starts with Y-pipe into a Borla stainless steel racing muffler (straight thru) going back to a large Dynomax Superturbo Muffler and chrome tip. The large 3" tip is not rice because I have the mechanical cajones to back it up Hope this helps. Davy Quote Link to comment Share on other sites More sharing options...

pparaska Posted October 16, 2001 Share Posted October 16, 2001 When I had an L24 in my Z, I had Motorsport Auto's 2.5" system on it with a Sonic Turbo muffler in the back. It droned like crazy. I added a 2.5" bullet muffler in the tunnel (it had two pipes in it and was packed with fiberglass, more of a muffler than a glass pack) and it help ONLY a little. Be careful with pipe sizes. If you only need 2" or 2.25" for good flow, stay away from 2.5". Quote Link to comment Share on other sites More sharing options...
