MattFransonPA Posted September 2, 2008 Share Posted September 2, 2008 A couple months ago I started hearing a rattling/vibration sound coming from the muffler on my '97 Pathy at 5-10 mph. 1 of the hangers on the rear resonator (?) came off and I put it back on but the sound still remains. As of the last 2 months when I go up hills I have to put the pedal to the floor and the muffler or resonator (not sure which or both) makes a loud sound (as if I had no muffler at all) and I thought maybe the baffles broke off inside and are clogging the muffler/resonator thus preventing the exhaust to leave and not allowing proper acceleration. I don't really know. I didn't know the rear muffler was a resonator until recently. I thought it was a catalytic converter Any tips? Thanks.

01LE Posted September 2, 2008 Share Posted September 2, 2008 I would say that is a pretty good guess. But it could also be a plugged catalytic. Or a bad MAF would cause the systems your describing. Link to comment Share on other sites More sharing options...

rod_b Posted September 2, 2008 Share Posted September 2, 2008 Thanks, what is a MAF? Mass Air Flow sensor. It's on the intake right after the filter...I believe. Link to comment Share on other sites More sharing options...
MattFransonPA Posted September 3, 2008 Author Share Posted September 3, 2008 Is the resonator also a catalytic converter? I looked under mine and it appears to have a central muffler and resonator at the end. Link to comment Share on other sites More sharing options...

No. The resonator is just another muffler to tone down the sound. Link to comment Share on other sites More sharing options...
MattFransonPA Posted September 6, 2008 Author Share Posted September 6, 2008 It's the muffler. Anyone know a good online parts place? Link to comment Share on other sites More sharing options...
csutke Posted September 6, 2008 Share Posted September 6, 2008 i would look in to an aftermarket muffler like flowmaster or manaflow and get rid if the resonator Link to comment Share on other sites More sharing options...
02silverpathy Posted September 6, 2008 Share Posted September 6, 2008 Go Aeroturbine!! I am trying to get one right now as my rear resonator section fell of last week...yup at the flange!! Go 3.5 exhaust!! I have a coworker that got one on his 04 F150....I can verify that he got another 3-4 MPG out of it!! Granted this is on a V8 but so what just swapping a muffler no pipes nothing else--cut--swap---weld, this beats up on Flowmaster as he did not change diameter of pipe just the muffler.

MattFransonPA Posted September 10, 2008 Author Share Posted September 10, 2008 $119 plus s/h is the cheapest I've found on ebay. I looked at alot of mufflers that were cheaper but none had dual inlet. I hate messing with exhaust and would rather put a cherry bomb on it but not sure with the dual pipes.

MY1PATH Posted September 10, 2008 Share Posted September 10, 2008 take some measurements and then get a magnaflow from summitracing.com Link to comment Share on other sites More sharing options...
MattFransonPA Posted September 11, 2008 Author Share Posted September 11, 2008 Thanks but I checked summit before and the only dual inlet they have is also dual outlet for $92 and I need dual inlet/single outlet. Link to comment Share on other sites More sharing options...
