alec_b Posted March 3, 2012 Report Share Posted March 3, 2012 Any 60* GM engine will sound like that with anything other than a brand new factory muffler. Most are whisper quiet. It doesn't take much to open them up though. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted March 3, 2012 Report Share Posted March 3, 2012 IIRC, GM didn't start adding resonators for a while, then all of a sudden, everything had them. Quote Link to comment Share on other sites More sharing options...
base93lumina Posted March 3, 2012 Report Share Posted March 3, 2012 Yeah, my 93 Lumina V6 didnt have a resonator, but the 92 Z34 i pulled the exhaust off of, did. From what i have seen in the yard, 95 seems to be the year Chevy thought a small resonator was to be installed on every car. You will also notice that the all the MPFI V6 equipped cars, have some kind of low toned rumble to them out the tail pipe, while all the newer cars (starting with the 3x00 motors), all have exhaust that just sounds like air moving thru a pipe.

94 olds vert Posted March 3, 2012 Report Share Posted March 3, 2012 My 1991 Grand prix does not have a resonator. My 1994 Cutlass Supreme (LQ1) did have a factory resonator. Quote Link to comment Share on other sites More sharing options...
LuminaPower92 Posted March 3, 2012 Report Share Posted March 3, 2012 Love the way the 3.1 sounds. Quote Link to comment Share on other sites More sharing options...
Cutlass350 Posted March 3, 2012 Report Share Posted March 3, 2012 (edited) IMHO, unless it's a V8, be very careful not to have a RICER exhaust sound: Â Oldsmobile Intrigue 3.5 exhaust mod examples: Rice, rice baby: Â Â This one sounds decent: Edited March 3, 2012 by Cutlass350 Quote Link to comment Share on other sites More sharing options...

Addicted To Boost Posted March 4, 2012 Report Share Posted March 4, 2012 My old 91 GTP didn't have a resonator either. Actually none of the 88-91 GPs I've had have had resonators. I think that's another 94+ thing. Quote Link to comment Share on other sites More sharing options...
paulo57509 Posted March 10, 2012 Report Share Posted March 10, 2012 My '92 Lumina 3.1L Euro has the "sport" exhaust system and does not have a resonator. Just a cat and a muffler. The dual outlet pipe muffler came on cars with the "sport" exhaust. It's pretty noisy. IMO, it's rather annoying. Quote Link to comment Share on other sites More sharing options...
