After 50K miles, my MRT up-pipe decided it had enough. I have been getting this loud clacking sound for about 2 months now. First I thought it was the Borla header. Then, after taking it to Mastro, Kelly walks into the waiting room holding my up-pipe. If you hold the one end and shake, it rattles back and forth. You can see the carbon on the outside of the flex unit. The excessive heat from the exhaust gases just wore through the flex unit.



I really thought MRT made good up-pipes,(I've even recommended them) but 2 years and 50k miles proved me wrong.
