Just wanting to know if anyone has any proof of the gain's " reducing Lag" from going to a cutout before the cat? I'm putting this 57trim kit on my car but im having issue with the stock turbosetup already about creep but this could be due to just the stock setup.
What I'm getting at is so that i dont have to get a larger exhaust im thinking about getting a McCord 3" cut out for 100$ and putting it right before the testpipe. I've seen a few dyno's but #'s arent as important as efficency to me with this. Should I even bother? BTW Noise is not an issue
