Dude, that sounds awesome, and I love your car by the way, my jaw drops everytime I see it in any thread. One more thing to compliment, I never noticed, but I like how you painted the black parts of the taillights to match the car.

Niiko, that thing sounds badass! You need to get a clip of your car doing a flyby down Kennedy road or something this summer! Maybe I'll catch you at the Timmy's on the weekends...

Sinister, what exhaust are you running? It sounds nice and crisp.. whereas my flowmaster sounds deep and loud... time for something new!
Also, do you have a picture of your display/spec board? I'd love to read it and see what it says..

Sinister, the car looks/sounds awesome! So that part number HZ-#9428 will fit my IROC fine?

I seen your post over @ls1tech.com. Your car sounds awesome also!

That's the piece that I have in the car...mind you I have a griffen radiator which is a little thicker than the stocker, it will fit but if you have a regular radiator in yours then you should also check out the # 9427 just to make sure
you shouldn't have a problem!

Yeah that's the Edelbrock S.T.B. and it's exactly like yours...carburated motors, the TBI one is mire flat...squarish like, I had to bash the front underside of mine to get it to fit around the water neck, I think that later this year I'm going to modify a bit by cutting the front part of it an re-weld a new tubular piece to get it closer to the air cleaner...move it up about an inch.
