I got a MLM Techno Circuit EDM pipe a few months ago and have had to weld it together a few times already. I really like the pipe itself, good take off and pretty good medium range, top speed with it was 47mph once down hill going full speed tuck and WOT. Average around 37 and can hit low 40's most of the time.
The baffle was pretty loose on the pipe and instead of being smart and getting a stronger spring I tried tack welding it on and now it keeps breaking at the baffle and have had to re-weld it like 3 times.
It also hit the peddles slightly and scraped some paint but that's not a major issue. The bigger issue was the belt hitting it when fully verriated (I can't figure out how to spell that) so I had to put a nice dent in the pipe to get it to clear the belt.
