is there a packaged deal with the catback exhaust :)

Looks great George!

I will definitely be interested once tuning becomes readily available.

We can definitely work something out once our production exhaust is completed.

Thanks for the compliments! I will be sure to let you know once we are done tuning on the 370Z, it isn't going to be an issue :)

Those look really nice, George! What kind of gains can one expect from them?

Thank you, the gains will be the same as our previous test pipes, since the resonator we use is pass through (won't create any back pressure).

Hey these look pretty damn nice!

Pictures + Dyno + Decent price = Good Job Sir.

Im going to be looking for test pipes soon. Waiting on sound clip differences between resonated and non.

We haven't had a G with stock exhaust with these on yet but a customer of ours is going to be installing these pretty soon, I will link the vid when available.

Thanks guys!

Sorry to be a pest George, but what type of steel are these made out of?

Keeping this in mind!

Does this come with the O-ring gasket?

Not being a pest at all, I forgot to list it! It is 304 Stainless Steel.

-George
GT Motorsports

No it does not, we could provide one at an additional cost if needed.

So do you just tell people to re-use stock O-ring or do you feel you dont need one at all?

Also, I'm sure you've heard that 2k-3k rasp/flutter from the test pipes...How well do these pipes dampen that noise compared to say, the HFCs ??
