i4 exhaust success from generic Alibaba

Appreciate the insight on this. I only did the exhaust and that's how I knew about the V clamp on the bottom. However, I know a few people have struggled with the DIY for the hi-flow downpipes that are available. So this should help a lot of folks.

Now your next mission, let us know if or how you solve for any CELs. Size spacer, mini cat attachment, etc?

I’m expecting the with Mach5 down pipe to not have CEL, we shall see after receive my 3” muffler clamp today from Amazon

This will be interesting given every other high-flow downpipe manufacturer has yielded multiple CELs. If it works, Mach5 should see a spike in sales in North America.
