Hi guys, just wanted to show the new valve-controlled axle-back by KKS-Performance
I've got a button to control the valves autonomous.
Downpipes are the next thing to come these days :-)
We have not made WOT runs as the car is factory new and nit run-in.
The reving-noise was raised from 93db to 108db with open valves.
Closed valves mean stock noise levels.
Here's some more info:
it's a 3" axle-back, it doesn't make sense to change the piping from downpipes to rear axle as it is full 3" stock and has 2 very very small mufflers.
The biggest restriction are the downpipes with 4 (2 on each side) restrictive catalsysts.
I'm getting new SS downpipes with 2 (1 on each side) 200cpi metallic cats.
No engine light, a decent hp gain and more noise is promised :-)
KKS delibers a button or remote to control the exhaust .
The stock exhaust valves open/close at certain rpms or WOT so you can't control them the same way like the KKS exhaust.
That's the big difference between other bolt-on exhausts and this one.
The weight is same as stock as far as I can tell.
