Is it a 200 or 250 (170?)?
(2 inch vs 2.25 pipes/system, also there may B diff suggestions on the mufflers).
I understand 'long tubes" R 4 Tq and "shorties" R 4 HP…?
I C a few (not many, but they R by the main co.s) mufflers with a "2 in" and a "1 out".
I'd like to use one of those 'new" band style exhaust clamps. It will not crush the metal of the flange.
I am hoping I can test the muffler on the vehicle for sound. That is such a personal choice... I would lay under and hand fit it for a few seconds and if sounding appropriate, clamp it on & get out-from-under for further listening. I'd take it off so as not to commit myself to the purchase (unless it seems right & going on to further testing) as I would not want to create a condition disallowing another sale. Each further test (continuing time on the vehicle) brings the muffler further from a store return. Having another rev the motor, doing so myself, clamping on a tail pipe, etc...
