hey i recently crashed my jato3.3 i thought i only broke the front arms and servo saver wich i replaced and fixed but then noticed i some how kinked the exhaust header will that affect the perfomance? also i wanted to get some new upgrades for my jato what is the best pipe you can but that will give my jato better performance?

yes that will afectpreformance due to less air flow.

Best Pipe i have found is a THS pipe. and it comes with a headder.......

Nailed the neighbors mail box post with mine at about 50.  Broke everything up front and the upper chassis.  Upgraded to RPM arms and shiney shafts.  Not sure why, but it sounds turbocharged or blown now.  My guess is the shiney shafts.

I would stick with the stock manifold. It's not like you will be able to tell the difference between fast as hell and I can't see it anymore.
