sounds great - wonder how long it takes to tire of all the drama?

it did not take me long to tire of Soul OAP + slip on.

NEVER!! 😁

took me about 1/2 day ... A BIT LIKE SOMEONE WHO LOST THE CAP LOCK KEY AND TYPES EVERYTHING IN CAPS ... IT GETS RAPIDLY "TIRING" (IMO)

Did anyone try the Cargraphic OPF delete -

CARGRAPHIC Otto Particulate Filter Replacement / Housing Set

it’s described as a hollow housing without filter with increased torque/HP and no drone. Seems interesting but I am wondering what is the science behind if there is any...

I have a set of those on order to replace my Soul OAP's ... in the hope that I can find a happy medium w/the Akrapovic slipon so watch this space.

p.s they are *not* cheap! about 2x the price of other OAPs

DocMo

Can’t wait to hear your experience with drone and performance. Why did you specifically choose these? Is it the only option in the market that reduces drone with the Kline OAPs?

Larry Cable

not sure about the Kline (I have no experience with them)... but having gone with the Akrapovic slip-on in combination with the Soul PP OAPs I needed to find something less SHOUTY than that combination, so instead of doing the smart/cheap thing and returning to the OEM OAPs
I decided to throw even more money at the problem and get the CG optimized flow OAPs which should fall somewhere in between OEM and any of the "straight thru" aftermarket solutions like the Soul (or others).

only time will tell if this is the sound combination I am looking for or not...

I would think that the silenced JCR OAP would be effective for drone reduction...

Larry Cable

and probably also a similar reduction in VOLUME as well ... which is what I am searching for...

The JCR silenced pipes look really nice. Looks like they are using 200 cell cats as silencers/resonators. Does anyone know how the flow of a 200 cell cat compares to the flow of the stock OAP matrix?

DocMo

There are no pictures, and it is not obvious on their website what they use on their Titanium silenced OAPs. I don’t think it’s 200 cell cats but rather a silencer or resonator of some sort.
the 200 cell cat OAPs are made with Inconel and need to be installed with their Inconel Race headers

I have the Kline rear and side pipes on order and someone on the Kline exhaust thread just got theirs and will install this weekend. Its funny because the OEM sound does get better/louder (im at 2500 miles) and from the bystanders already holding their ears as I drive by... Im wondering what looks im going to get up and down my street with the new stuff!

The new Cargraphic OAP's got rid of the can and added heat shields.

I’ll be installing a valved and silenced JCR exhaust today and tomorrow, and I think I’m going to absolutely love it .
Will report back , hopefully with some videos from my 105dB track day at Laguna Seca on Saturday.
