I have a 93, Im running 11.90's naturally asperated. For exhaust Im running Hooker full length 11/2" headers to a 3" H pipe and out 21/2" pipes to 3 chamber flows dumped. Works great for me. This is the best way to go but the hardest, I pulled the front gas tank so I could have a true staight dule exhaust system that freed up at least 30 hp that where getting robbed by the y pipe set up.
On my 93' Im running hooker full length headers through 40 series 3 chamber flowmasters and it rattles pictures on the walls, if you want louder than that then go with two chambers, and evan louder then go with simple one chambers either way they really free up your exhaust and they make plenty of racket
i didi it while waiting on my bassani cat back. it sounded great, but was too much for any kind of highway driving. it actually cancelled out my stereo, and would literally rattle your teeth. it did sound cool as hell from outside the truck tho.
