Don't do ETA's. Never end well (for me). Engine cover is pretty much gauranteed to be released before the brace though and is simply waiting on ample release quantities to arrive. Braces have a much more elaborate story behind them and a few more hurdles to cross so will likely lag behind a bit.

No difference. G80/G82 base and competition all use identical factory part numbered exhausts.

Couple things:

- Should have included an indexing pin for the tips (something manufacturers don't seem to think about for zero reason and is quite an annoyance to precisely equally rotate the tips).
- Should have created the axle-back and midpipe to fit most midpipes on the market, as the interplay would have been a huge selling point. Your instructions say to cut at the middle dimples on either side, but a majority of midpipes (Valvetronic, Active Autowerke, Eisenmann, MAD) use the 1st dimple on driver's side and 2nd dimple on passenger's side.

I would have purchased this axle-back if the second point was true, since I was planning to pick up AA's equal length midpipe.

Looks oddly similar to AWEís setup. Keeps the stock emissions in place, Iím sure itíll sound amazing. But, same fear as removing the emission lowers or catless DP, it will probably drone and be obnoxious.

i was hoping for removal of the secondary cats and no cutting. simple bolt on setup... for those of us that wants this, will you make an extended version of the midpipe?

No, as that would require removing the secondary cats and ultimately lead to hefty fines for violating emissions requirements. As a public company that would be bad. Very bad.

A lot of manufacturers/distributors are able to bypass this by selling the product as "track-only" and requires you to sign a waiver.

Private entities can do whatever measures they want to, but again that is not an avenue our board, and ultimately our investors/stockholders, wish to mess with for a host of different reasons that I will not get into on a public forum. The fact is the larger the company, the more reason to be leary as the fines involved can easily cripple the business. Doesn't mean we necessarily like it -- its just the rules we need to play by. That said, Dinan has always been about emissions legality (30+ years of EO's) so it's not a new position for us either.

Used to be a big Dinan guy until they outsourced to Taiwan/China for everything. I put 2 exhausts on a x3m that both rattled at the valves and couldnít be fixed so they were returned- garbage exhaust from my experience. Went Akrapovic right after.

Secondary cats on our g8x cars are non monitored and I can assure you I passed emissions with a single midpipe from AA this year. I also had on a VSC-valve controller. Fuck the gov even if it was a problem

Anyone who makes a single midpipe. Us included should be using the factory cut points the same as dinan does for their axle back. This 100% will mate to our single midpipe. Looking forward to getting one of these systems for our g80 to make some videos.

Thereís three factory cut points on either side marked by a set of dimples. Most use what I explained. Perhaps it might mate? At that point youíre just hoping the pipe clamp is long enough.

They prettt much all do- I highly recommend AA, perfect fit and the mid pipes are made in the US. Sounds amazing.

That's what I'm trying to decipher as well. The single mid look to cut the front of car dimple on the driver side and the mid dimple on the passenger.
This exhaust if mated to the factory center section would cut the mid dimple on both sides.

I feel like this exhaust wouldn't reach an aftermarket center mid pipe by about one dimple length.

A clamp would need to span that distance.

Can anyone actually confirm a fitment this way, I would lean to speculate that it DOESN'T fit rather than Fits, but I wouldn't know til I tried.

Iíll let you know Friday. Having the axle back fitted. Currently have a full TFL system and my biggest worry is where the two will join and if one is shorter than the other.

Yes. Already is emissions legal by nature. Does not alter/remove cats so therefore does not require CARB/emissions testing.

Just mounted the dinan axle back to my existing TFL system. Thankfully it fits. The link is tapered and slips in to the exiting pipe so for those out there with just a mid pipe this should fit. Fitment was good but issues with tightening the outer tips proved difficult. Had to mount, then mark where to titghten, then drop the exhaust a little to make room to tighten. It actually took longer to mount the axle back than my original system all together! Lol other than that I like it so far. Has a deeper tone but Iíll get more time in the car this weekend.

As for the silver tips, Iím on the fence. Theyíre definitely shiny and the reason I went with silver was to match the wheels coming in a few months. But who knows I may just get the black ones later.

A few pics and some revs in sport+
