Default ISF aftermarket exhaust availability

What ISF exhausts are still being produced for aftermarket? I know Xforce, Borla, RR Racing, I really like ISS Forged and Joe Z but not sure if they're still being made. Not interested in Greddy/HKS.

I've been leaning towards RR
Every other site doesn't have or doesn't do a good job of listing our vehicle with anything available
Case in point above...
I'm almost leaning towards a custom fabbed at this point with the lack of availability and the gold plated cost of some of the ones that are out there.

I just purchased a new Joe Z catback from Mod in Japan last July 2022.

I spoke with Mod in Japan today. The PTS Joe Z exhaust is discontinued for the ISF according to them.

All of our options are available but built to order. So the lead time is going to be around 6 weeks. Sometimes they come out a little quicker.

1. Quad tip full catback (with cat options)
2. Quad tip Axle back only
3. Bazooka full catback (with cat options)
4. Bazooka axle back only.

See link for more details.

The PPE dual mode valved exhaust is great and should still be available based on this link: https://shopfigs.com/v5/PPE-exhaust-ISF

Yikes, that's a typo lol!

In all seriousness though, the GESI cats are totally worth it. They easily dealt with 1 track day and multiple hard canyon runs over the last 6 years.

A guy local to me has the PPE dual-mode exhaust and UEL Headers & she is an absolute screamer. The PPE exhaust is a great choice. His F sounds really good. With the valves open it is a lot louder than my Xforce and UEL Headers.

What are you doing about the headers being in CA for smog?
