I ended up with the wrong version for my trim level. Never installed, but it is slightly used. Comes with all of the hardware pictured and includes the cup holders/keyless dongle (not sure what it's actually called). $300 shipped to the lower 48.

Less than 2000 miles on this practically new converter. I ended up switching to the 258mm since I'm now a boosted application. Packaged using the same materials they sent my new converter in (very thick foam). You don't have to wait 2+ months like I did for mine :). Reference...

I've cross-posted in the HPTuners forum, but that usually takes a while (if you get a response). Figured I'd post here to see if anyone has a suggestion. I have a 10R80 with a CircleD 245mm. The lock up RPM and shift points are fine. The issue is when it does lock up, it really-really grabs the...

My [very limited] understanding is that cats need temperature to work effectively, but boosted applications cause too much heat and start to break them down. I'm curious if anyone has any data on moving them further downstream in the exhaust system? This is for the smell/sound benefits since...

2019 Mustang GT I'm striking out on finding much information for instructions on how to R&R the fuel vapor tube(DR3Z-9E325-A). I had a shop look up the steps and they said it required removal of the fuel tank. I'm curious if anyone has done that and has a write-up or video anywhere (removal of...

Switched to a Whipple and the buyer of the Roush Supercharger kit already had the air intake. This is just the box and the elbow from the 2018-2020 Roush Supercharger kit. Only has ~5000 miles on it. One minor blemish on the air cleaner window. Fits stock throttle body. No hardware. Local pick...

Stock take off after only 50 miles. Had the dealer install a Roush supercharger and it does not go back on after the supercharger is installed. Local pick up in Austin, TX. Willing to ship if buyer pays. $75 obo

Stock take off after ~7,000 miles on the car. Has one [very] minor blemish. Buyer will need 3M tape and the nuts/hardware. Local pick up in Austin, TX. Willing to ship if buyer pays. $150 obo

Stock take off after ~7,000 miles on the car. Has the typical micro-scratches under the GT emblem (the picture is very zoomed in). Local pick up in Austin, TX. Willing to ship if buyer pays. $75 obo

Cross-posting (probably should have been in this forum anyway)... I've entered to run my first Texas Mile this weekend. I've watched a few videos, but if anyone has any preparation tips, I'd appreciate it. Also, if anyone else is going, it'd be great to meet up. Current car specs are in my...

I've entered to run my first Texas Mile next weekend! I've watched a few videos, but if anyone has any preparation tips, I'd appreciate it. Also, if anyone else is going, it'd be great to meet up. Current car specs are in my "showcase/garage": The Sleeper | 2015+ S550 Mustang Forum (GT...

Roush Stage 1 Supercharger Kit for Ford Mustang 2018-2020 GT. Includes Roush coil covers. Only has 6,000 miles on it (swapped out for a Whipple Gen5). Installed by Mac Haik Ford, removed by Pro Modular Performance. Asking $5,500 for local pick up, but I am willing to ship at the buyer's expense.

I was wondering if anyone has seen any "SC" fender or decklid emblems in the 2018-2019 font/typeface? I had a couple of Ford Thunderbird SC's back in the day and since my car is supercharged, it'd be cool/different to have those instead of the 5.0 emblems. Any leads or thoughts on where to get...

Kind of quiet in here :). If someone in the Austin area was, in theory, looking to swap out their Roush SC for a Whipple or Edlebrock SC, is the only option ProModular Performance? Just curious if this area supports more shops with knowledge of our cars + performance mods? Plus, it'd be good...
