Yes , I think it was an inaccurate build on the headers.

As far as the more restrictive headers, if you have the stock 2" mufflers then I don't think a switch is necessary, however, my Harley has 2" headers and mufflers and that's just for one cylinder.

I think if I had stock Superformance 2 inch mufflers and the older restrictive header I would leave it alone as the change to big headers and 3 inch exhaust only seemed to make a difference above 3500 rpm. It was fast enough before, but I already had the big header so I just cut out the 2" exhaust and added 3 inch "Chambered exhaust" mufflers. Plus, I really just wanted a heartier sound when I did the mufflers in the first place. Like I needed more power?????

Panavia...I bought those bolts with the little half moon and clip.....hope those will work. AND one last question....do you see an issue with the clearance ...would you still use a gasket with that? thanks
