This will work good on your AT coupe, Motordyne 5/16" spacer is a proven winner. Installs in about an hour with a torque wrench, read the instruction carefully! ART pipes will give you a free flow exhaust, if you don't mind the stinky exhaust! I prefer Fast Intentions HFCs, way cool sound and you can breathe with the windows down. Transgo kit only if your trans doesn't shift quickly! Headers work very well if you intend to go FI, they're not worth the $$ which is the opinion of all but a few members here.

Alright. Think Ill be having friends over to help and see the outcome anyway.

Thanks for all the advice but.

What is the lifetime of motordyne tdx exhaust by the way?

Forever in the southern states, ten years in the frozen north or Canada if your car is garaged!
