I added OBX Stainless 1-7/8" primary longtube headers and high flow cats last weekend, now my exhaust is all 3" from the collector to the tips.
Made a huge difference in power by my "Butt Dyno" ..LOL
Not much difference in loudness at idle and low rpms.....But sounds really Goooood from 4000 rpm and up !!

Still collecting up parts to do a Camshaft swap in the next month or two.
