If you're an A4 then the stock gearset would be 2.73 (GU2) with 3.23 (GU5) being the optional gearset. Check your door info to see.
Best all around gearset for an A4 is 3.73. Get AAM gears if you can. Richmond as an alternate. I don't want to cause problems but I've had nothing but gear whine out of Motive gears.
And if you do a high stall torque converter stock 3.23's will work just fine.
1st: SFC's, SFC's, SFC's... You want to be able to close the doors down the road yes???
2nd: TC with associated tranny mods. This includes a cooler.
3rd: LS6 intake manifold.
4th: Exhaust. Lots of ways to go here.
At this point you'll probably have to upgrade rear suspension cuz it'll be romping real hard. See my sig for details.
There are way more things to do but think of doing these first.67 Camaro: K-K + 797-z (look it up), 454/Th400/4.10 12-bolt = 6mpg, PS/PDB/PW tilt, tach, gauges...
2005 Corvette LS2/M6 Magnetic Red Metallic (What else would it be?) w/ Cashmere interior
2002 Z28: NBM/Tan, MTI smooth lid, smooth bellows, !AIR, !cats, 1-3/4" QTP SS LT's, 2-1/2" TD's with X-pipe, MagnaFlows dumped at axle, custom welded SFC's, MidWest Chassis body mount adjustable T/A, 3400 stall, 3.23 gears (was 2.73). Tuned: 343rwhp/357rwt (before TD's). Best: 12.559 @ 108+, 1.73 60' @ 3500' DA w/MT ET Street DR's.
Carbon footprint? CLOWN SHOE!

Bolt on SFC's are fine and can always be welded later. We have UMI 2 point bolt ons installed under our car. They definitely make a difference. If you are an autocrosser, or plan on having a tunnel mount torque arm, then check out the 3 point design. I will also put in a plug for UMI -- they make great stuff.

3.23's on a stock stall suck. I feel like I'm waiting for boost half the time

my richmond gears are noisey as hell. but the exhaust is loud enough to drown it out most of the time. sounds like a turbine on decel..i just tell passengers "prepare for lift off, this birds goin too the moon!"

gears and stall

According to the calculator gears with a 17" rim
2.73 at 70mph =1751rpm
3.23=2072 (About right in my car)
And 3.23's are out of the question so take your pick

Port the throttle body, leave the mass airflow sensor alone. What exhaust from slp, unless it's the dual dual muffler or the lm2 I advise against it for 2 reasons
2. Lm-1 with headers suck

Well for bolt-on autos I am trapping a 108mph at the 1/4mile
3.23's at 110mph=4652
With a stall I guess the trap speed would go down a bit, but I like to think if you want to top out on third gear at the end of the quarter it looks like 4.10's are the best bet. I know stock for stock 3.23's yield roughly .2 e.t faster times at the track. And my 3.23's are just getting back into the power band at the end of the quarter.

They are based off an auto calculator on another website. This assumes you have a 17" wheel and a .7 to 1 overdrive. 1/4 mile ones are 1 to 1. My car does about 200rpm at 70 mph, compare it to yours.

If you ever get headers it will sound like ass.

What do you mean by one catback sytem? They are are all basically the same style except borla and gmmg.
Borla being it goes straight in on the passenger side and exits the driver side, with the adjustable plate being on the passenger side.
And gmmg being chambered or almost a straight through design.
Most other catbacks have one in and 2 out design and will flow pretty close to each other with the exception of flowmaster's 80's series for our car.
Edit I think I know what you mean now, they only make the one catback kit for our cars, if you want custom then that's a different animal-like my magnaflow duals
Mark at kyspeed sells the magnaflow kit.
