GT4 and Soul Performance Long Tube Sport Headers Review

I haven't been back to Laguna Seca yet still...but our cars will break sound even OEM there... so already I was lifting and up shifting a gear and moving over to left side when I passed sound booth before I added header... I imagine same technique would work...that or else a GPS device like you say.
As far as power, you are saying it is worthwhile? I realize going with race headers is the ultimate, but I really want to keep cats and avoid having to swamp the muffler, so these look like an interesting alternative.
I don't think it is that loud from a normal sound booth type of distance. 123 db must be having the mic right next to the muffler tips.

Yes see my original video above...first that was dbA not db so there may be a slight difference but either way that was like a foot or two from the back of the car. The sound booth etc would be much further away of course.

I also have the Soul cat back exhaust on another company's headers. That company's cat back was great at high revs, but had an oppressive drone between 2 and 3K. It made the car oppressive in regular driving. The Soul exhaust eliminates the drone, raises the PSE tone moderately up to 3.5K and gets positively grand from 4K on. I can't imagine not including it with the header change. It reminds you why you bought a manual every time you shift.

Rather than start a new thread I’ll just add to this one. On the strength of this thread, and MComet having pretty much identical goals to me, I opted for Soul Long Tube with cats and Softronic tune. My goals: Keep the same sound (tone and timbre) but amp it up a little bit when the binoculars button is pushed. Be able to go into stealth mode in the hood or when I just generally want to keep a lower aural profile. ZERO drone (had it with two different 911 Turbo aftermarket exhausts, it was deafening), eliminate the flat spot in the power delivery, and as a bonus get a few more ponies if it happened, but even if it didn’t I’d be okay with that as it wasn’t my primary objective.
Called up John Gaydos at Soul and had a nice succinct convo with him. That’s who steered me towards Softronic. He was familiar with my shop (the owner runs Soul headers on his 991 GT3) and said it was a good idea to have them order it, which I wanted to do. I placed the order, backlog was about 3 weeks. It all came in and I had it installed and tuned (and plugs replaced while they had the header off) on Thursday.
MComet did such a great job describing things in the OP that I won’t wax poetic myownself, other than to say that Soul has delivered exactly what I was looking for. Zero drone, authoritative bark of the flat-six under half or more throttle, docile sounding at low throttle or with the binoculars button not pushed, flat spot absolutely gone, no CELs. The only thing I haven’t confirmed is not tripping sound meters at the local tracks (Road Atlanta, AMP, Barber) but having heard cars that passed there and now this Soul header, I really don’t think it’s going to be a problem.
Fantastic product! I’m just sad I can’t see the things, they’re so beautiful. Where’s that plexiglas engine cover??? (I guess you still couldn’t see them. ) Well done, John and crew!
