Cat back exhaust testing should be complete this week.

Thanks guys!

pics and sound clips please.. :]

Here is the first version of our 2.5" GTM cat back with some dyno results and some pics, The car made 308 RWHP and 261.1 RWTQ with adding 2 degree's of timing via the consult III. The 370Z counties to impress us by how well it responding the modification we are making. We will be finalizing the GTM ecu flash for the 370Z within the next 10 days and i have no doubt that we can get other 10 to 15 RWHP with some tuning .

We have another week to finalize our GTM 3 " exhaust then we will move to the turbo kit .

Stay tuned

Sounds fantastic as well. Preliminary price point, $1500 - $1800 with test pipes?

Now this is how you show results.

P.S. What were the sparks flying out the back?

I think the next thing you guys need to do is weigh the exhaust. Its not going to be titanium like the Japan brands, but at the same time, it won't cost $4500 bucks.

Those numbers look great. You didn't loose any torque and in fact gained! Any idea what kind of numbers this would do without replacing the cats? I plan to keep my car smog-legal until I do the turbo.

Nice!! Who turned out the lights :icon18:

I hope you guys can keep the cost reasonable, with so many people making SS catback exhaust for the 370z it's going to be a tuff choice.

I like the numbers and torque curve I'm seeing, I want something that will give some gains in the lower rpms as well. This car seams to need it, doesn't really come alive until after 5K RPM, and for a street car it would be better to have power come in a little lower.

Keep up the good work :tup:

PS: I know you guys are working on a TT for this, but any thoughts of a NA intake as well???

I am impressed with the sound of the dyno pull that you have on youtube with your custom catback and test pipes. It sounds great! Power gains are very cool too, but I wish you hadn't added 2 deg of timing to get real results of the catback alone... Looks great, sounds great. If the price is right, I don't see why not.

Make a thread about the new catback or I'll steal your thunder and make on myself!
