At the moment, I am getting all the parts together for the next round of upgrades for the beetle.

Any recomendations for the best flowing exhaust for a 1915/2000 cc motor? It needs to be the best flowing while still meeting the 92 db noise regs for places like mount cotton.

Volks.com.au, have the A sidewinder pretty cheap, and was thinking about getting one? My current (empi?) 1 5/8 inch full merged with fat boy is getting a little old in the teeth and doesn't meet the noise requirements.

Engine is a 72mm by 94mm motor (2L), wedge ports, 48's and 130 Engle cam and 1.25 rockers. Redlines at about 6500 rpm max.

I used these mufflers for circuit racing ,lasted for ever and sold it still perfect when I parted out my car....

Keep your exhaust and when you go to your next event just take a large hose clamp and small piece of pipe and clamp the pipe piece on your tip facing the opposite direction to the noise level meter. Problem fixed, cost zero.
