I have a currently stock 1998 Trans Am w/A4 and 3.23.

What size cut out do I get? I want to order a Qtec.
Also anyone kno where I can find a pin diagram for the F-body convertible top switch? I am planning on using this for the electric cutout. If I could get a pin out on it it would save me alot of time.

Thank you

 

3" cutout for stock exhaust and all 3" catbacks.

 

Wow! Now that's speedy service!

Gonna go order one right now.

 

Yeah these guys are super quick with help lol, 3"
