I ran BBK headers on my 03 GT back in the day. However, I'm a huge fan of the stainless power 1 7/8 headers for their price point. I'm going to be doing a set on my friend and customers car this Saturday. They're going to be paired with some Corsa Xtremes.
there are some slight differences between the collector size (2 3/4 vice 3) from what I have seen. I have a set of SPs in the garage and compared them side by side to my SW headers. They are a quality header for sure.
my wife said I dont smell when I come in from driving the car. The interior of the car doesnt smell like fuel either. :shrug:
I can smell a little fuel smell when I park but thats about it.
I run the SW factory connect long tubes no cats on my car with the Corsa sports. I installed them myself on the car and the quality and fitment was spot on, as stated you cant go wrong with any of the big name brands SW, ARH, Kooks.
I ran a TVS on 12 at 669/581 for almost 32k miles. drove the car across the states twice. never had any issues. the only reason I got rid of the car was to get my 15.
