Side Pipe SPL

vector1, certainly one way to go although not as user friendly as the PVC Mock-Up Kit offered by these other guys http://stainless.eclipticcms.com/customheaders

What I'm looking into now is corrective measures for a "too short" primary pipe length. What! No, I don't have that problem - just turning over more rocks. I think I can safely say "exhaust system engineering" is a lot like RF - freak'in BLACK MAGIC. Well, I'm an RF guy and I see some interesting parallels with exhaust systems and RF signal paths. (Yes Richard, I'm thinking WAY outside the box now). Being the savvy EE that I am, on more than one occasion electronic packaging has introduced unwanted VSWR to RF circuits (impedance mismatch - components in too close proximity to each other). In those instances, by screwing around with the circuit path downstream you can sometimes tune out the VSWR mismatch and get the throughput you want. So I'm looking at what corrective measures are out there with 4-1 collector designs, muffler lengths/diameters, and even primary ID tweaking to bring that mismatched exhaust system back in. Hey, it's all fun.

Looking forward to ...

Oh yeah, and this other thing that's bothering me - that rear header tight bend right out of the gate, can you say restrictive? vector1 agrees with me too!

Why don't you guys mod that inner panel next to the footwell to buy some needed space?

Anyone ever look at all that room these JBL's have in front of the motor? Damn, almost looks like you could start those headers off looking like a GT40 setup, then wrap 'em under to a collector behind the front wheel? Wow, get your optimum primary length and a clean single pipe exit to boot! (This one is a real stretch, someone slap me upside the head!)

Ok, I'm done now lol.
