I got mine for around $600 off ecs tuning and it was the last one they don’t carry it and I believe the price has bumped up to the $800’s on the actual CG website. I felt a difference... larger diameter and less restricted cat with no cel.

I got mine for 500 from ecs. They had one in stock as a scratched item which is why i got it for such a good price. Took my chance and it literally was a very minor cosmetic scratches. My mechanic installed it and it’s amazing.

I almost got that one too, but I'm sensitively picky so i ended up with a new one. The AFE is probably the next best choice on the market not sure if it triggers a cel or not, but i think a lot of the high flow catted do not i could be wrong though so far we know the CG doesn't.

You're PM box is full.

I was recommended to your down pipe but I first skipped over it due to lack of information on fitment on the F33 / 440XI convertible. (Your site doesn't show it available...)

I thought I would reach out and verify if it would fit or not?

If so, can you also send me pricing?

Thankfully yes. Did some additional work for me late last year (2018).

I have their custom Downpipe and Exhaust.

Much of their stuff is custom made to order now.

In case anyone out of state is interested, I have my CG 5" catted down-pipe for sale. Since i installed meth on my car i went catless.... its fun when others see meth flames coming out of your tail pipes.

Had mine for well over 15k and no CEL and very minimal smell. You don't notice it.

I've only gotten a CEL once after running a Stage 2 for a few weeks. I cleared it and it hasn't come back on since. I think it was an anomaly. I've been running it for almost 2 years now and it's been great.

One recommendation to all: the stock burble tune is very aggressive. Long term, that's not good for our cats and to replace one now would be nearly $1k. Not cheap We should probably turn down the burbles. I actually like how BM3's burbles are toned down from OEM. I plan to reduce it further.

I just had my CG DS1 catted DP installed a week ago on my N55 F30. It's been great. No CEL. Improved the sound and performance noticeably. My favorite performance mod.

The downpipe bracket was totally off though and could not be used during the install. Not sure if that's because it was welded in the wrong location by CG or designed for B58. Either way it's secure without mounting the bracket.

I ordered it from ECS and yes they specifically asked for my vehicle specs on the phone for their order from CG. Everything fit nicely otherwise.

Anyone know if there there any issues running this without mounting the bracket?
