I have Megan LTH on car for 3 years now with no fitment or weld issues. Before that Megan shorty headers for 4 years with no issues.

LTH will only be beneficial if running larger cams otherwise wasting time/money installing them.

 

Finally had a chance this am to go to the shop & work on the car...got it all fixed, including new welds to the holes in the left tube where the bracket came off & new o2 bung welded in the collector...I see why the welds broke, this piping is paper thin...I took pics of it all, will be contacting MR & sending pics & a letter to them...Depending on their customer service response answer, will determine what i will do with them After I take them off in a couple weeks. If they do nothing, I'm gonna run them over with the F650 & crush them, then put them in a box & send them back to MR...
