New Build: Shelby Cobra Daytona Coupe CSX9126

[Pliskin]

Duane-Yeah I don't think I'll be disappointed at all. Tom did not notate the sheet with those specifics...I just have a straight printout from the session. I can certainly find out though.

Twin-Thanks for the compliments on the car's look. Glad to hear it impressed an observer in the way I intended. My Wife and I have been using words like sinister, stealth and menacing to describe it for quite some time.
There are two ways to configure the exhaust system on a 9000 series coupe. Naturally the quad side pipes are integral to the look of a Daytona so they are present with either setup. First option is to have the side pipes as ornaments, basically, then they route the real exhaust system, pipes, mufflers and tailpipes to exit holes cut into the forward portion of the tucked under rear valance. This quiets the car considerably. On my car the side pipes are fully functioning, much louder and this avoids a few extra pounds of piping and, important to me, no holes cut in the bodywork. Look at the photos in my album, click "Pliskin", top right of this page, there's a shot of the pipes back from the coating vendor and you can make out a full length chamber that is behind the pipes, unseen, when mounted. Added resonance and depth to the tone.
Personally, I can't imagine building one of these cars and wanting to muffle it's character. It is a Cobra after all and should be loud, rude and in your face...no apologies.

A word of advice.
A professional builder friend built a FF Daytona and powered it with a 650HP stroked FE. It's primarily for track and he immediately noticed that the motor hit an RPM wall about 5000 and determined the 'stock' Coupe quad small block sidepipes were too small. He fabricated basically a 427 sidepipe and found 6800 RPM again. Totally different on-track power.
And adding 40-50 pounds of undercar pipes won't help.
If appearance is all that matters, ignore...

Chas, my point exactly. I've "heard" the quad pipes kill 50-100 hp in stock configuration.

Yes, I think they're at their limit near 400HP-like on the originals.
