I ordered the lethal X-pipe today. I don't feel like much needs to be done. The stock cat back is so good.
Thanks for your business! We really appreciate it!

@JakeLethal could you also inquire with Corsa or SW about doing a slip on double H for our cars?
We're working on making the Corsa Double HH and XX available for the 2020+ GT500's. Shouldn't be long before we have it figured out and available to the public. Stay tuned as we'll most definitely post about it once they are ready. These will be just like the ones for the GT where they connect to the front using the factory clamps. On the back side of it you'll need to cut the catback piping and use the supplied slip fit adapters to connect the HH/XX to the factory piping.

What does the Lethal X do to the Sound?

also what do you think the Corsa Double HH and XX are going to do to the sound?

Here's a video of our resonator delete X on Ken from Palm Beach Dyno's car.

As to the double HH and Double XX I believe they will sound similar but possibly a slightly deeper tone due to the longer 3" section the Corsa pipes have as well as the HH tone being different from the X.

That’s awesome news, you can put me down for a HH pipe! Can’t wait! Thanks for looking into this!

Call me crazy but I want a single H pipe. One exactly like the X pipe, only an H in its place.

Hopefully they’ll do sound videos so we can have a good idea of what they’ll sound like.

Same. Would love to see this offered from someone that has a workable product.

I guess if you use the lethal race pipes you probably need a tune because you’re going to be deleting the catalytic converter. I must Resist the temptation for now.

Anybody using the lethal race pipes? How is your experience?

I would guess the car becomes insanely loud with that change!

We're just wrapping up our car from the Whipple install. We put some 2" Stainless Works headers on there at the same time. Those paired with the Corsa catback system is ridiculous!!! We just shared a video of it on our Instagram @teamlethal pages story.

The SW catback is tempting to me because the factory tips on my exhaust are BS. Couple of scratches and appear to be low quality in my view. SW makes some premium kit though, would look nice.

So does this have the lethal X pipe delete in the middle or does the cat back system go all the way from the headers

“Cat back” means it starts from behind the cat to the tail pipe.
