Your results from a full Delkevic exhaust, please?

Hi gang,

Has anyone here put a full 4-1 Delkevic exhaust on their Gen 2, and also had it dyno tuned? If so, could you please share what gains you saw over stock? Many thanks in advance!

I'd imagine it would be similar +/- a couple hp/tq figures...most add 8-10 hp and maybe a little more in conjunction with other bolt ons and a flash...

I dare say it’ll be on par with a lot of the other brands.

Anywhere from 5-15hp with a decent tune.

I went from a BW 4> 2, then into a Delk 4>2>1 with a Yoshi CF can. Although the Delk was a nice pipe, I wasn't that happy with the build or result. The BW headers were much better quality in build and welds.
I dropped quite a bit of Midrange and high RPM going from the BW to the Delk. I got it all back, plus some with a Akro 4>1 system. I'd get my dyno charts, but I'm working interstate for a few days..

the downpipes are small in diameter - hence the poor performance

buy cheap and you buy twice
