Just need to know the highest boost leve/pulley size to safely run with my mods:

3" Smoothed Bends From cat-back
Magnaflow cat
80 series flowmaster
180* t-stat
4" mandrel bent CAI w/ K&N Filter

Thanks guys... i was ready to order the 2.5" for my bonneville cause that seemed to be the agreement from reading previous posts for the 94-95 series one m62 supercharged motor.

2.5" sounds right.

With that 3" exhaust, you could possibly go a little smaller, maybe, but I would probably stick with 2.5"
