Very impressed with all aspects of the purchasing process. Very simple and straight forward ordering online. The equipment shipped within 36 Hours of purchase, and arrived in perfect condition.
Once the stock downpipe was removed, the relatively simple. The final bolt is difficult to work with, due to the bell sitting so close, you have little to no room to utilize a socket or box wrench, otherwise it was smooth sailing. The performance boost is certainly noticeable versus the stock downpipe.
Already had the CNT catback which sounds and looks fantastic. Now that it is matched with a cattted downpipe the revs and launch control sound unbelievable. Install the was easy and straight forward just do the bottom bolts first. Thanks CNT!
I bought the CNT 3" catted downpipe for my 2011 speed3 because its basically cobb quality for half the price. Install was awful but the results are unreal. This downpipe along with the AP stage 2 ots map has turned my speed into a rocket. Literally a rocket and the exhaust note is louder and deeper. Sounds ungodly in fact. Very satisfied.
Heard good reviews from previous owners of this product. I knew I wanted to stay catted with my build so I saw that you had the cheats price so I went for it. And man am I glad. Install was super easy, and it makes my car SCREAM!!!!!
Performance- pipe is great. Good welds, didn't see any flaws. Only problem I found was during install. The bellmouth is so large and close to the bolt holes that you can not use a socket on the lower two bolts. I had to use a wrench and a crows foot because of the little room in there. If this was fixed I would give 5 stars.
