New 2010 535i M-sport. What next?
Just got a used 2010 535i M-sport with upgraded trans with paddle shifters. The car has JB4 chip, Remus quad exhaust, and Dual Cone Intakes.
I'm trying to figure out what route to go next. I'm thinking of going with a aftermarket larger Intercooler and charge pipe with blow off valve. Or should I go with catted down pipes first? Which will I get the most out of?
With straight down pipes with no catt, does that cause the engine like to come on?
