Will be right about $1500-1600 range for the catback.

GTM_Challenge · 08-15-2012, 05:30 PM

Just an update: We are currently road testing our down pipe with high flow cat in combination with our catback. So far we have about 300-350 miles on the car and no check engine light even...

Crossing our fingers at the moment that we may not need an ECU flash to trick the car with our high flow cat version.

The Catless downpipe will need ECU flash or another work around to get rid of the O2 sensor error.

NateDog07V · 08-15-2012, 05:39 PM

Nice! Are you shipping the exhaust systems yet? Also, do you have any in car videos of idle, cruising around and WOT? Thx!

GTM_Challenge · 08-15-2012, 05:45 PM

We are taking reservations for the exhaust, they will be ready to ship in about 3-4 weeks. We are doing videos today, once they are edited we will get them up. Please PM for more details !

Newest video:

Challenge Sport catback Exhaust with Challenge downpipe with High Flow Cat. The downpipe added a good amount of grunt down low and in the midrange without adding any additional noise at crusing speeds. The cold start is now a bit louder than before and the over all exhaust note is a bit deeper with a hint of turbo noise in it

When the Ecu is put in sport mode, you also get a bit more burble and poping noise off throttle

Sounds great with the catted downpipe. Can't wait to get this. So no dash lights because it is a catted downpipe correct?

No CEL yet with the high flow cat downpipe with the 350 miles or so yet. I should be putting another 200+ miles on it this weekend and see if its still off. We're pretty shocked it hasnt popped up really.

Rich@GTBPerformance · 08-16-2012, 05:16 PM

Absolutely loving how that exhaust sounds! Can't wait to get our hands on one!

Any updates at all? Still no light?

We're about 600+ miles into it. No CEL with the HFC downpipe so far. We'll likely release it with a notation that with the current ECU version it shouldnt trigger a o2 sensor code. We'll get the ECU map version from the dealer. BMW likes to update the maps sometimes but you can choose to not update them for example.

What is the pricing for the down pipe? Will it still pass smog?

J-boogey · 08-27-2012, 04:02 PM

will you have a catless DP as well or just HFC?

None of our exhausts are CARB exempt etc. We don't have smog tests in this area, so i cant say if it would pass by you with the HFC. It's a 200 cell unit. Most states now only require an OBD2 scan for a clean bill of health.

Both catless and HFC down pipes will be offered. Catless ones will require a tune for sure though to cancel any O2 sensor error codes.

luigimaster24 · 09-03-2012, 11:08 PM

When and where can i purchase these downpipes?

itsbrokeagain · 09-04-2012, 11:48 AM

Whats the chances of you making a chargepipe to replace that flimsy plastic one? We have had a huge number of issues with the e9x n55 pipes blowing apart at stock and higher boost levels.

The downpipes are a few weeks out yet. We will make an anouncement as soon as they are available.

We'll take a look into this. Definately something we can do though if there is a need for it.
