I didn’t realize that the Kline headers didn’t add any power. If that’s the case, it’s just for slightly more volume then?

I never trust the manufacturers dyno charts as all you have to do is tweak perimeters or test on a cold morning and you get the target output. While I have not tested my car, the headers with 200 cel cats are definitely noticeable. As with any car that I have added headers, the engine revs much easier and seems to climb faster through the range. I do have a tune but that was installed before the headers. Of course it sounds glorious--enough that when I went to get my ceramic coating maintenance, the owner asked me what I did to the exhaust as it sounds amazing. So, he remembered the car from a year before and noted the exhaust note change. A year ago I only had the inconel OAP and rear muffler.

Well I have been going back and forth between Kline and BC Fabs and finally bit the bullet and put my order in at BC Fabs after speaking with someone who has their system in UK and says there is essentially no drone with great sound. He sent my a clip. I order the inconel opf delete heat shielded oap and their inconel valved exhaust. Hopefully in will be here in 6 weeks and I can install it quickly. Will let you know how it goes. video/audio clip was in mp4 and converted to mp3 and landed up with just audio.

Most people I spoke to didn't choose that system because the valves closed path is basically dumped straight out with no mixing of the banks, so that's the sound you're going to hear 80% of the time unless you have a valve controller. It is like the stock valves open system - straight out.

I am first going to try it without a valve controller and who knows I just might be adding one. Stay tuned, I'll let you know what I find besides my wallet being lighter.

I've asked the same question several months ago with little in return that helped... I assume this is due to the limited amount of people running headers on the 4.0.

Black Friday is around the corner, so I'll be making moves on a set of Kline Headers in SS (not Inconel to match my system) - from whomever offers the best deal. These can currently be had for $3500.00. I wanted to go with SOUL for my headers bc I feel their design is better than Kline, but I cant justify the nearly $2000 price jump, even if they squeeze out a few more HP.

I cant speak on behalf of a before and after when installing the collar mod since I placed them on immediately, but I can say that I truly enjoy the tone throughout the entire rev range with my flaps full open.

I also think it has too much of that bassy tone, as opposed to the higher pitch (which I personally prefer) and the Kline does well.

I've been thinking about making this move as well - do we know if there's any downside to "mixing" the metals used at different points in the system? I also have the inconel OAPs and rear section, but they're even saltier than the SOUL options you refer to above. If the SS options really do add some additional noise and hopefully some oomph, then I might end up going that direction. Because an SRS is likely not in my future.

I feel Kline is the best all-rounder. I do think though, other systems have a cleaner higher pitch under load. Kline has the side can mufflers and a decent sized muffler which (presumably) prevent that, but their benefits are why I purchased the system.

Can anyone confirm what else (other than OAPs, tips, and muffler) should be included in a Kline system? Ie. what nuts/bolts/etc and quantities.

I purchased mine used and want to make sure I have everything I need for the install.

I think I finally was able to get clips uploaded correctly. I also like higher pitch. Hope it works out for me. We shall see.

where are you located for those of us in your area who may want to hear it?

I'm in south Georgia little over a hour north of Tallahassee Fl. Hope to have it in 6 weeks.

I took a ride this weekend in a local Rennlist SS Kline Spyder... and there isn't a single video or recording that captures this exhaust adequately... (and I've watched them all)...
