cartman Posted January 12, 2015 Share Posted January 12, 2015 I am thinking about Cobb stage 2 in the next few months (cbe, downpipe) and sti uppipe. Car has been mine since new, running stage 1 for abot 100k miles. Runs good with no issues. I hesitate to do it based on mileage. Any advise?

compsurge Posted January 12, 2015 Share Posted January 12, 2015 Do it. You'll wonder why you didn't do it sooner. I guess the only real concern would be if you wanted to have emissions as good as factory, then you'll need to keep the factory pipe or get a good GESI high flow OBDII legal cat. Other than that...
