look at my signature and then tell me what next: ssra or lt's

 

LT's...that shouldn't even be a question.

 

do you only have $200 or do you have $600?

pretty easy to chose

 

LongTubes

 

None of the above.

M6 you should get a new shifter, skip shift eliminator and 4.10 gears.

A4 you should get 3500-4000 stall torque converter, tranny cooler and shift kit (SK is optional).

A4 or M6 I would definately do LT headers after the above mentioned mods.

Good Luck

 

LT's!

 

If A4, Torque Converter.

If M6, LT Headers.

 

Gears! M6-4.10, A4-3.73. You really must think about how you want to run your car first b/f you add a high stall conv.

 

both...ssra and LT's...

and yes, if you have a m6, shifter and skip shift
A4 shift kit

 

Definitely LT's. I did 4.10's before that, but I really wanted some acceleration. Id say either gears or LT's. Cant go wron either way.

 

Long tubes, definitely. and gears after that.
