I recommend getting the soul valves controller bypass.
- cheap
- works perfect
- 2 settings (like Cargraphic) still keeps the oem PSE map and bypass to full open whenever wanted.

Also for the people who complain about the 2-3k rpm drone in mostly valved exhausts its noticeable and felt when the valves are closed and less obvious when valves fully opened.
its mainly due to the flow of exhaust hitting the small muffler boxs and valves in it so your choice either annoy the people outside when you drive and have much less drone or have valves on and annoy yourself inside lol

i have several people who has ridden with me in my car, a person who loves after market exhausts and some volume from his car enjoys my rides but for people who are quite and love to drive quietly especially in the city they hate the sound that my car produces.... those people would even love driving EV for life not because of efficiency but because of silence

The drone is also present in exhaust system without valves, like the Soul Race system (with or without resonators)...try it myself.
On sound...well there's loud, nice, sonorous, proper Porsche sound and then their's loud, obnoxious, raspy sound......I love the first one but these cars can fall into the second one very easily.
This is very subjective but IMHO these cars need something in the exhaust path to attenuate the sound.....it can be loud but has to sound nice....still looking for the solution to this.

Yeah, what he said! Cargraphic FTW!

This is why I love our working relationship. I go on here and make suggestions whose replies make my brain hurt and then you call and we have a technical discussion and make a plan. And it works!

I have your ECU flash my friend and I may even discount the crap out of it given your support from the Caribbean!

Hi John...need to talk (or e-mail) about that ECU Flash.
IMHO you can run race headers and OAP with or without a resonator or cat...what you really need is a rear muffler that's light, mixes both banks and if possible with valves.
The Cargraphics Racing X looks like a very good candidate but want to see what else is on the horizon.

you'll be 100% satisfied with this set-up. let us know how you like it!

will do - just waiting for the CarGraphic "flow optimized" OAPs (w/heat shielding) to arrive from Germany (within the next 2 wks or so, 4-6 wks from order to delivery), then I will replace the Soul OAPs with the CG pipes ...

I'll do a Db comparison of the two combinations ...

Looking forward to it

That's what I thought, sometimes people change things and I didn't want to make comment without knowing the current configuration. So mine is nearly identical to what you 'had' the very slight difference in pipes silenced versus non-silenced is less than 1 dB, the other difference is that I can let the OEM PSE take over and help keep the drone at bay with closed valves and a silencer in that path.

I might be the first one installing
1. Dundon street headers
2. Cargraphics valved race/x pipe exhaust.

U probably are. Im going a similar route with the bc fabs street headers and cargraphic touring muffler. The headers make it LOUD
currently running aftermarket headers n stock muffler

jacksot

That should sound amazing! When is the install happening?

No Name

Getting the Dundon street headers tomorrow, when they posted the slightly used one on sale, snatched those up real quick. Just waiting on the Cargraphics exhaust from Eric, Supremepower, I believe they are on a 2-4 week wait times.

Hi Larry -

so it sounds like you’re running Soul OAP in compunction with stock set up otherwise at the moment? Sorry - difficult so sort through all the comments but I tried. If that’s the case and you’re switching to a different brand, what didn’t you like about the Soul? My GTS is affected by the stop sale so spending my time trying to figure out the right set up.

thanks
Alex

Looking forward to the results.......
