As long as the system is properly installed you won't have any issues. Dinan did a great job on their R&D to ensure smooth increase in power and boost at all speeds. The system is VERY sensitive so you may get a drivetrain error if the outside environment abruptly changes, but that is solved by restarting the car.
Only complaint is the cost, but that's what you get for their warranty.

I am thinking of Catless DPs, but I am afraid that it would void the OEM warranty.
Any change in sound and/or performance with the new DPs? Getting a CEL?

Thanks!!!

I will do the stage 1 for sure!!!

The Super Sprint Catless Down Pipes were installed by my dealer at 2000 km for just the cost of labour ... was a freebee for the parts

As they installed it, they said they would warranty it as well

I have a GREAT Relationship with them (BMW, MERCEDES, AUDI, Porsche, VW, Alpha Romeo and Subaru all under one ownership here on Vancouver Isalnd and I know the owner well and his staff ... and business relationships go both ways, referrals, and then the volume of cars I purchase through them)

The sound with the catless downpipes is louder and the turbo spool also more noticable ... feels quicker by butt dyno as well

I only occasionally get the CEL ... and only under WOT ... next start up and civil driving and its gone.

Will pull trigger soon then re Dinan Stage 1 ... not sure of Stage II and intake upgrade yet... did you do stage I then go to Stage II?

Thanks Buddy!

Oh, the folks at Dinan_Engineering (in my other thread re "Dinan Advice - Do I pull the trigger") also said that the SS catless down pipes will add another 15 to 20 hp as well ... And the sound and turbo spool is much deeper as well
