UK S2000 Exhaust Mod

We'd like to share some of the performance work going on the shop today -- the UK S2000 exhaust mod. This mods diverts a portion of the exhaust flow past the first part of the twin-loop muffler for a more pleasing exhaust note without the typical droning of common aftermarket exhausts for the S2000. We use a 1" stainless U bend and cut to fit. Here is a picture of the tube held up for fitment check.

Next the we grind the opening for exact fitment.

We've had lots of requests for dyno results after the UK S2000 exhaust mod- so here ya go. The customer AP2 S2000 is equipped with a header and test pipe and tuned using a Hondata K-Pro. Blue line is with the stock AP2 exhaust, the red line is the UK mod AP2 exhaust. A slight increase in power with the UK mod, but most importantly the exhaust note has improved dramatically. Nice and mellow without any harshness building to a pleasing wail at 9000 rpm- just what the customer wanted...
