First of all i'd like to introduce my self to the group, I'm Robert from Los Angeles, CA, and i am a proud owner of my first Z! I was wondering what was the best exhaust to put on my 94 TT, i want more torque in 1st and second gear cause i want to have fun with it on the Auto Cross or Solo courses. Is there a difference in single 3-4" tips vs. double tips on the exhaust? Which maker makes the best exhaust for this car, i have heard B&B is a good one, but i'd like your opinions.. Thank You!
