Hopefully the delete will help out. Let us all know.

You mean more drone compared to oem exhaust with PSE working (closing/opening valves) or both all the time with the valves open?

Thank you!

inconel. Stock headers

to be honest i notice NO drone. I will take a video at 2800 rpm this upcoming weekend. I get annoyed at droning especially when we used to have a 718 cayman with AWE exhaust. God that was awful

There is no more drone with the Kline exhaust than OEM. Its about the same. The tone is deeper when valves closed and higher pitched with valves open... but the drone is virtually the same.

Has anyone experienced engine warning light after fitting 200 cell headers?
I've had mine for a few hundred miles but a light came on recently. Not sure if it's the headers though,

NiteCrawlr

I don't have the headers (yet) but was thinking about installing. I have heard the 200 cell are not suppose to cause a CEL. Does anyone have the 100 cell or know the real world differences between the two? Does the 100 cell offer some performance benefits at the expense of being street legal or at the expense of daily livability?

MannyLon

I found that 200 cell headers do not make any performance improvement by themselves.

Please elaborate. I thought this was the one exhaust mod that really DID make a difference ??

@MannyLon I suppose you don't have a dyno run from before the headers went on? I'm wondering if there's some negative interaction between the Kline headers and the BCF muffler, or if your motor is just on the low end of the power output spectrum.

MannyLon

Kline say that BCF won't be causing any issues. My car should have produced a bit more power, as ~405bhp is on the threashold. I know that RR is a rough figure, but it was tested against a similar model.
For Kline you need the whole systen to see any gains.

I spent a decent portion of the morning driving behind nitecrawlr. Absolutely loved listening to his car. The howl up the rpm range was great. I was surprised how loud the pops/cracks were on shifting. They also sounded very good. I found myself intentionally staying in a lower rev range on my car to better hear nitecrawlr’s car. It’s the first time I’ve been able to hear a 4.0 with a cat back exhaust from outside the car. Needless to say, I’m still in the aftermarket exhaust makes the 4.0 experience better camp.

Totally. Cat back at least is the second most needed mod (the first being adjustable toe links to get the alignment under control). I have the Kline cat back system in inconnel and drove behind my car in a Spyder recently and the sound from my GT4 was soooooo goooood! Surprisingly a bit louder than I expected and was happy about that. Driving at 6000 to 8000 RPM with windows down thru an extended tunnel is like being at an F1 race.... Its just bonkers! Highly recommend. There is also some power gains though minimal.... the car breathes better and BMC filters help too with sound and breathability.

Any of you guys with the Kline system do the sound symposer delete yet? Would love to know your thoughts on the difference it made. Thinking about ordering the inconel OAP and rear section for my Spyder to built this month.
