There is a lengthy thread on this site about people with downpipes and stalling/idle problems. I am considering a Dinan stage 2 with cat back exhaust and downpipes but that thread made me very worrisome.

I love downpipes on turbo cars but the fact that most piggy back systems and Dinan do not incoporate software to compensate for downpipes worries me. Adding downpipes to a turbo car changes the flow characteristics and air fuel ratios quite a bit which combined with a software "flash" that doesnt take this into effect can lead to lean mixture right?

On my Nissan GTR, adding downpipes made a HUGE change to air flow and this required large changes to injector flow to compensate for a safe air fuel ratio otherwise the car will run extremely lean. Downpipes= tune mandatory. I know these are two totally different cars but how do you compensate for the downpipes?

None what-so-ever...runs perfectly aside from the SES light caused by the catless DP. I have a JB Can Tool set on auto clear for that though...only pain in the ass is inspection...because im 2012 I cant find jack shit that will allow me to bypass the 02 and catalyst monitor "ready" status on the OBD2 test...

No problems with the set up though.

Oh and it sounds MEANNNN. I get a ton of compliments. And I also get a few people who think its obnoxious...

I have the Berk resonated mid pipes on now, before I had the n-55 mids w/o resonators and it was just stupid drone on the highway and startups set off car alarms in my garage...planning on putting another resonator just after the DP or between the mids and the cat-back
