I went with Dundon, their products are always one of the best. Currently waiting for mine to arrive, hopefully Fedex can deliver on time this time.

That's my car. BCF rear box does not really affect the result as another 718 was tested at the same time. Kline have told me that you need their full system and a ecu tune to gain the best from their system.
I have since removed the Kline manifolds..

Has anyone gotten a CEL(s) when running Headers with the high flow cats?

Which headers did you switch to?

Do you think I’m better off with Kline headers to match the rest of the system or is there a better option?

I plan on using the M-Egineering tune

I have dundon street headers. For the win.

quick note. You have the oap backwards.

And just because one has a higher price does not mean it is better...

No wonder the car feels slow! JK : ) This was just for photo purpose.

HAHA. I figured, but made me laugh when I saw the picture. Car and exhaust looks great.

I hope you like yours, I heard Matt's from obsessed garage...and I didn't like the sound. Obviously sound is very subjective and everyone has different tastes. The other great thing is that we have lots of options. Please post some videos for us to enjoy!

yeah I posted the videos on exhaust thread. It has the full Street headers with the car graphic race exhaust. Screams loud above 5k, has drone, I am sensitive to it but learn to live with it after a few days of driving. But I like the sound a little bit way too much and the car pulls hard for me to put it back to stock.

M-Egineering tune, is that a remap?
The 200 Kline headers do sound great, but I was left dissapointed with the lack of gains.
Yes probably best to have the same matching components.

I've ordered JCR manifolds and rear as I think they sound best..

I went ahead and ordered the 200 Kline but I already have the rest of the system. I’m primarily interested in sound but would like power gains as well. I was worried about mixing/matching as I don’t want a system that is too loud or drones obtrusively and worst case I didn’t want to buy a set of headers and have them just not be compatible with the rest of the Kline system.

I reached out to Kline as well who told me the best power gains are if you have the full system but didn’t tell me how much power or that you needed a tune to optimize.

jcmer22

Yes the M-Egineering tune is a remap to maximize the exhaust changes. Sounds like it really wakes the car up.

Klines headers have very short runners unlike Cargraphic, jcr, soul ect. I don’t want to leave any power on the table that’s why I’m unsure about using the Kline headers. I have no issue with mix matching components.

JCR is excellent, but was quite a bit more expensive. Good luck with your setup.

jcmer22

If I’m going to replace headers I want to do it primarily for the HP gains, but I also want the car slightly louder. Klines short runners are very different from the competitors and I’m hoping this isn’t a negative.
