I'd love to see an interior driving video of that system. Congrats on the car and the new sounds!

Give it some more miles and I think your ears will aclimate. I’ve driven 1000+ miles now since adding the headers and I don’t think it is that much louder anymore. Valves always open and sport exhaust button always on. Initially my ears were ringing at higher revs but the same happened when I added just the exhaust/oap. Definitely sounds better in the lower rev ranges with the headers and definitely more power.

if anyone thinks the exhaust/oap combo is already great but wants more, or if you don’t like the sound at lower revs - try the headers I doubt you will be disappointed.

True. But his report of drone was from 5000-5500....and he had a hard time defining it as "drone". I have never experienced that. And that range is so "transient"(IOW I go through it so rapidly) that if it is there, it is very brief. I mean who cruises around in that range for very long?? Usually when you are going through that range it is in transition with the hammer down. Maybe the next time out I will intentionally go "looking" for it.

Unrelated to what we are talking about above.....I just took an hour drive. One other thing about this exhaust, and probably others, is that it is somewhat of a solution to the long gearing. I guess all I am saying is that it sounds so damn good when you get to 6500rpm you feel the instinctual need to shift as it is screaming at that point(6MT Spyder). If you stay in it to redline, the world is ending. Yeah I know. A bit melodramatic. But the point being is it makes the lower RPM ranges MUCH more enjoyable without the need to feel like you have to stay in it to redline. But when you do.....yikes!!!

Still after awhile of driving... the BRAP BRAP BRAP at lower rev range of 3 to 5k with valves open at WOT is fairly intense. Its really so clean and beautiful now closed then open at 4k. But either way its just heaven the way the car is now. Stomp on the gas and it is just an explosion of sound and fury - really amazing!

This is the video I was referring to, all this is fresh in my mind after going through my own experiment with an exhaust. He notes drone in the 2000 range which is right in the zone. I would think it would be less of an issue with a soft top and top down.

flynlo

Well the only thing I can say is it does not exist in my car or I am not hearing it. Maybe he forgot to turn the Cylinder deactivation off??? Yeah, it drones like hell in that range regardless of the exhaust. But I am here to tell you I hear nothing of the sort. It may just be me. And again, next time in the car I will go "looking" for it!!!

Come on @flynlo it's been over 18 hours, you must have gone for a drive by now!

K-Nut

I drive with full exhaust 200 cell cats with open valves all ways , it’s not bad under 4K , over 5 it’s just superior , loud and lovely !!!!

Stupid work. I’m out flying around. Did a charter yesterday and another today. Currently sitting on the ground in Topeka KS waiting for the lady Baylor Bears BB team. Back to normal flying tomorrow. I won’t be able to get out until Tuesday or Wednesday at the earliest. But I’ll let you know. I’m positive it’s not there though. It sounds just awesome in all ranges IMO.

Westcoast

I don't feel sorry for you, one of the things I always wanted to get was my pilots license, you're flying around the country (making money I hope) probably having a blast, then you come home to a couple of pretties, I've seen the pictures.

Hey @K-Nut thanks! You and Pete are the main reason (as well as the support and encouragement of others!) I went with Kline and then all the way to the 200cells. So happy with the full system. Its also sounding better and better as I drive it - the ECU tune also does not hurt. Maybe thats a reason why the sound for me under 4k WOT with valves open sound just a touch harsh on the inside... I need to take some videos. But overall Kline is working out way better than I ever expected and this mod has made the car even more special.

I had the joy of spending the day with my family at The Shop, a local car club I belong to with full garage/tools/lifts, etc. We all went there to install my Kline OPF/Muffler…my two boys to help and my wife to take photos. We got the car up on the lift…always a challenge with low cars, and then had brunch while the exhaust cooled. I’m happy to say it was a success! It took us about 4-5 hours but I’m slow and make a lot of mistakes. I’ll do a write up another time but overall, it was pretty straight forward. Some basic instructions from Kline would have made it easier but we plowed ahead.

The ride home was sublime. I’m loving the sound of the exhaust across the full RPM range. Never obnoxious, a nice low end rumble and a beautiful wail. I’m running PSE so I haven’t been able to hear what it sounds like open all the time but it still sounds great. More details, videos, etc in the near future but for now I need the Advil to kick in 😂

That's my kind of family outing
2-seater; who rode in the frunk and who rode in the trunk?

Jeff Jones

It was a two car caravan. The Volvo carried the exhaust and was there for any part or tool runs we needed to make 😃

For those that paid to have the OAP and muffler installed, how much did it cost / how many hours did they bill you for?

Im waiting on two inquiries, but I almost wonder if I should put the money towards a quickjack and do it myself.
