Exhaust Options
Alright guys, My 99 XJ has the famous manifold leak. It's been driving me crazy. I have a new header bought. While I am at it I am thinking on have a new down pipe bent to get rid of the smash in the factory pipe. What size should I have it done with? 2.25"? What are your guy's take on the smash/dent and what should I do about it?

I'd just swap the header on, you will probably notice more power increase/throttle response with the header upgrade, compared to eliminating the dented downpipe. Maybe if you were NHRA draggin, the time/money hassle to eliminate the dented downpipe would be worth it, my .02
