Hey guys,

I have a 2003 G35 coupe (6spd) and I'm going to upgrade it with an APS TT kit. I had a couple of questions out there for you guys as I haven't come up with a clear answer after browsing the forum.

1) With an APS TT kit installed, can I (should I) continue to use the stillen true dual exhaust and headers that I currently have?

2) The APS kit comes with a pre-tuned piggy-back system (I believe); can we modify the tuning, if so how? Do you guys recommend another management system?

3) My car has very little mileage on it (~13000miles), should I use up the stock clutch prior to upgrading, or should I change it now? If changing, the JWT clutch+flywheel seems well liked on the forum, would this be appropriate (for a street driver)?

4) Gauges - I'm probably going to go with Defi gauges (BF amber), but I haven't seen them in person? How well do these match up to our stock backlight?

5) Are the any major issues / precautions you guys have once going to this setup?

Thanks.
