Tune is indeed required to eliminate the CEL.

There hopefully will be a catted version down the road.

We have installed plenty of these now and know that these are currently the best fitting on the market.

Even with a stock exhaust it opens up both power and sound

We have sets in stock and can ship out today!

Someone correct me if I'm wrong, but is this company charging $3700 for a set of stainless steel pipes?

Has anyone purchased the primary downpipes only without the midpipes? If so, does it still sound good and would it deliver approximately the same amount of power as installing both primary and secondary downpipes?

I'll take a stab at this...

upper dp -> lower dp -> midpipe -> muffler -> tips

primary cats are on the upper dp
secondary cats are on the lower dp
cat-back systems include midpipe back to the tips
axle-back systems include muffler back to the tips

Removal of secondary cats (replacement of lower dp) won't throw CEL, but also doesn't do much performance-wise. More of a sound mod than anything.

Please step in if I've misstated anything...

They look amazing
Just one request can i get a set w/ a M instead of the K logo ? jk
I understand your are branding your product but Im sure the dealer would prefer to not see any logo .
make them look as oem as possible so less chance of dealers red flagging cars

Please excuse my ignorance if this has already been discussed, but what are the implications for emissions testing if you do lower down pipes only?

I have Keller lower dp and the eisenmann race exhaust. The sound! Is just awe. Only in wot does it get Loud. I think it's perfect. Pops and burbles like no other. Deep and aggressive tone . Keller all the way

Stock Mid Pipe?
M performance mid pipe that's had a resonator but basically it was the same thing just a tad bit more burbles and deep, but you wouldn't be able to tell the difference from stock
