Gets the job done at a great price!

The CNT Racing downpipes have been on my car for almost two months though. They allow me to tune the car to a more powerful map by removing the restriction of catalytic converters. I did have an exhaust leak that I just fixed with gasket sealer. I would recommend putting all bolts in place before tightening down any just to be sure they are lined up correctly. Overall, it took quite some time to swap them in, about 20 hours of work over 3 days, because the bolts were hard to take off of my 132,000 mile 2007 E90 335i. However if you do decide to get catless downpipes, I don’t see any reason to pay any more money for different ones. These are great quality and get the job done!

Works but the fitment wasn't nearly as good as the OEM was
