1989 Firebird Formula 350 425hp L98, T56, Magnaflow exhaust and more!

This is how my car now sounds 8-27-10. My car has a new 355 L98 with 10.5:1, AFR Eliminators, Lloyd Elliot cam (223 230 .535 .535 109LSA) and a TPIS Miniram. It runs flawlessly thanks to the OBDII PCM swap. Just installed a new McLeod clutch, "Dyno Don" headers and y pipe, and a fresh rebuild on my 9 bolt rear including new bearings, posi cones, and 4.11 gears. This car is tuned, but is cold, hence the crap out of the exhaust. I was not able to get video of the dyno runs but the numbers were 370rwhp @ 6200rpm and 350rwtq at 4800 rpm. Not too bad for now :-D

nice man sounds good , but gotta admit i prefer GMMG exhaust, I saw you had it at one time. What happen? Didn't like it anymore or complications?

@slasher7555 I had the GMMG for like 5 years. I got tired of it honestly. It was loud and cackly with my motor and was obnoxious. I just think im getting older. This Magnaflow sounds way better to me now, and plus I can hear my radio!

what all exactly does an obd2 pcm swap require

Yeah i got a 40 series Flowmaster y-pipe in gonna get the 3", 3"5 single in/dual out Magnaflow also, i think it sounds deeper and meaner than just being louder

that is fn awsome ! the gmmg is too obnoxious much cleaner sound out of the magnaflow.
