This past weekend, I put over 500 miles on my jeep and durring the process, I crushed my tail pipe on a trail and it's now pinched, similar to pinching and end of a straw. Since then, there is a noticable sound difference (obviously) and I think there is a slight performance issue. It may just be my imagination... but I swear I feel the jeep is more sluggish.

Could the "pinch" cause too much back pressure (even though there is still an openning) and in return make my Jeep run crappy? Or could it be a "too many miles in 2 days" type of thing?

(I am running a flowmaster 60 muffler)

 

That will definitely cause a loss in performance. Bend it back or throw on a new pipe

 

Thanks for the confirmation.
