2,5" stainless steel mandrel from cat to Magnaflow muffler +18 inch Magnaflow resonator

3" mandrel after header. Then 18"x6" or 18"x5" Magnaflow resonator into 8"x5" or bigger Magnaflow rear drum.

Remove cat (if law permits).

That what I have. Well I have the 18x6 reso & 8x5 oval muffler. With modded SSAC header, HKS filter 16ve cams (no cam gear) so not much gain there and Calum ecu. No other mod. Sr16ve flywheel with stock clutch and ACT pp. 184whp and 145wtq.

This is how it sounds:

I'm going 2.5" regardless for the street, and will be welding in a dump tube to use at the drag strip. Our local circuit track has a noise level restriction, so I have to keep it as quite as I can.
