can you guys post up a vid of the sound of just the test pipes WITH stock cat-back exhaust?

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.

A little cat substrate material

Here is a dyno graph of one run with the added 2 degrees and one without, as you can see the gains from the timing advance were minimal.

MSRP for this exhaust will be around $1,495.00, in polished stainless steel, with Titanium tips being optional for an additional cost.

Interesting. I assume that you're making a 3" cat-back for the turbo kit?

LiquidZ · 01-26-2009, 10:00 PM

Any updates on the turbo kit?

George@GTM · 01-27-2009, 02:55 AM

Currently we are working on the 3" Turbo back exhaust, and then the twin turbo system.

Fan-freaking-tastic! I'll have to add that to my list of stuff for you to do when you turbo my car. I assume you'll be tuning it for that, right?

Cown3d · 01-28-2009, 04:13 PM

it will be interesting to see a graph of the 3" on the NA app as opposed to the 2.5"
i wonder if youll lose much low end?

Crash · 01-28-2009, 05:29 PM

Without tuning, you'll likely lose enough to feel it.

TerribleONE · 02-02-2009, 01:31 AM
