Tom,
Your car looks great.....I love the no-rollbar, no-hoodscoop, no-sidepipes street car look.....I conceded to the rollbar and hood scoop on my car for open track events.
Your tips look similar to mine and they look good, but I like the look of the smaller diameter straight cut rolled tips best.
The dual chamber Flomasters are very quiet at idle, but anything above idle is pretty loud and WOT is very loud on my car.
I don't understand why you think shorty headers won't fit in your engine bay. A friend of mine has a SPF with a 460 in it and his headers clear the foot boxes, frame, and firewall okay. My headers are actually blockhuggers and that may be what you should look for.
Btw, I sent you an e-mail, let me know if you don't receive it today.
Mike
