Thanks for the information -- I'm definitely now leaning away from using a 2.5" muffler in place of the current 3" unit as I do not want any heat or back-pressure issues.

I'm thinking I'll take my car to another recommended exhaust specialsit here locally and see if he can get this new muffler in a 3" size to fit in my current pipe configuration. Then, at least I haven't gone "backwards" and will re-evaluate my entire set-up when I install headers at a future date.

Does anyone on this forum have experience with the Powertone exhaust tips? Supposedly, they have a decibel reduction rating of about 10 units and do not create any back-pressure -- ?
