bolts have nothing to do with leaks. but they supposedly upgraded their bolts from a grade 5 to an 8. I didn't risk it. I went out and bought the highest grade I could find at lowes.

This place by me Bridgeview Automotive Which is a small, but the only place i trust to do a set of headders right. They use hi quality fasteners with locks and after they installed those i had 0 leaks. Till i sold the car. Bridgeview automotive are absolutly the finest Exhaust shop too If you live in the chicago area and are looking to do a custome exhaust I highly reccomend them.

alright the install is done and the end results were worth the increase in low end torque and hp, i went with the 1.5" primaries and 2.5" dp w/cat but i know most ppl went with 1.75" primaries and was wondering what differences you noticed with that set up?
