C. Don't like antilag LOL

We decided to make a high quality cutout that is driven by boost, similar to our quick spool valve for turbos. Once you hit your desired boost level, the exhaust valve opens instantly, you do nothing, no switches, just let it rip. It closes automatically and you're back to your normal exhaust routing.

Here is a little video of the BIG 4" one we made for a supra build.
SP Exhaust cutout

We will be offering these in 2", 3", 4", and possibly some half sizes if needed.
We use full stainless so no worries on rusting, or bending like other products out there.

I'll snap some pics of it completed this week (waiting on stainless tubing to finish the rest)


Thanks
