hey torrie do the tunes that come with the purchase of the X4 customizable for things such as intakes, headers, and x pipes? or is everything just determined from a datalogged WOT?
I'm still skeptical of headers on the 15 v6 since I haven't seen any conclusive dyno results. Everyone who has got them says they "feel" a difference and the exhaust note changes but I'm pretty sure bbk has never shown numbers for it
There is a guy on here that had roush abs and x pipe and he had the x pipe removed cuz he thought it was too loud. I've had the roush abs for about three months I love the sound as is but just ordered the flown master x pipe cuz I want it to be louder
arfe you still running roush abs and xpipe? i wanna do xpipe next but need more feedback before i pull the trigger. i know one guy said it was way too loud
