BMW N55 Catted Downpipe is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Sounds awesome, no smell I've had this for about three weeks. The install went pretty smoothly with my mechanic saying the fitment was about a 8.5 out of 10 compared to OEM. With stock exhaust this is LOUD at start-up but settles into a nice rumble after initial warm up. Idle and coasting has almost no droning even in my convertible, but when I get on it it sounds like a F1 car! I love the rumbling and popping at low revs when coasting to. I don't really notice the faster spool up of the turbos but I've been tuning at the same time so it's hard to tell. I notice no smell which is good since that's why I went with the catted DP in the first place so for me the cost was absolutely worth it since I can't smell it even with the top down stopped at a light. Customer support was top notch too when I called about the gaskets (you reuse the OEM ones).

Rated 4 out of 5 by from Solid product!! 2011 335I N55... delivery was prompt/fast! unboxed the downpipe,no hardware! called Cobb,they were very proffessional and expedited the new hardware! set back installation a day and a half,no problem. i did the install myself in my garage,with jackstands. not the easiest of jobs but it can be done! $400.00 was the average install price around town. i was a little disappointed with the hardware that came with the downpipe,i was expecting better quality. the hardware that was sent had to be altered/grinded. the flanges on the bolt/nut were too wide to install on the exhaust pipe side of the downpipe. i didnt think about it at the time but i could have used the original hardware/nuts. other than that ,good product. i will be purchasing my Accessport soon and put all these after market parts(High airflow intake,FMIC,chargepipe,downpipe)to use!
