Tom,
I replied to your PM with my contact info. I'll send you an e-mail later today.
I installed out-of-the-box Sanderson ceramic coated 1 5/8" shorty headers on my SBC (but don't tell or the Cobra police will be after me....)
The rest of the system is custom made from 2.25" aluminized pipe run between the frame rails to Flowmaster mufflers and out the back through 3" chrome angle cut tips (not SS). I'd also like to change the tips to 2.5" straight cut SS (with rolled edges), but I'll have to do a search for them. I'm sure someone sells them.
Post a picture of your SPF, I'd like to see it.
Mike
