New set up

 

Old set up
U can clearly tell exhaust pulse is different

 

really nice. i like the design. i definitely hear the difference between the two.

what size are the primaries?

 

Taking easy on first Track testing
Shift at 7800rpm and some corner did not down shift

 

if you're taking it easy then it likely hasn’t been back on the dyno yet?
.

 

?

 

 

you need more shrouding if you want sustained track time, too much air going around the coolers and not inside. The more horsepower, more heat to shed - aside from that looks great, have fun!

 

Some dyno Graph with exhaust
TQ look fat and steady, car is easy drive with this set up but still thinking build a bigger merge collector

Car also come back from 5mo of frame of paint job with retro 80s group C graphics \(//?//)\

 

 

New merge collector pick up 10% more hp at same Dyno
