Sure, let me clarify why I posted what I did.
When you’re evaluating an acceleration mod (Stage 3) and it’s cost worthiness, compare it to other power mods (tune/intake/pulley/pulley/lw parts).
Adding in things like a catback exhaust (sound only, no performance) or headers (proven to add nothing) or meth injection (proven to be less effective than race gas) or high cost LW wheels (no more effective than stock 18" wheels) don’t really serve the purpose of your initial argument.
Your argument was, if I may paraphrase, that a B8 S4 owner may want to just go from stock to Stage 3 to avoid fussing around with all the annoying little steps to get to full on stage 2. Just pay one price and BAM…you’ve got a great performer.
The problem is that if stage 2 B8 S4 owners will get headers or catbacks or whatever you want to mention while going stage 2, those are optional. You shouldn’t add those in to the cost of achieving stage 2 performance because they’re irrelevant. If you do add them, you should then also add those in to the cost of going stage 3 because they’re just as likely to buy that stuff. So stage 3 costs $9000 for the kit + $2000 for cooling (is that right?) + $5,000 for headers and catback. That’s $16,000. Compared to stage 2 $5500 + headers and catback and you’re at $10,500. The delta is still $5,500.
I chose instead to focus on the actual performance contributors.
Make sense?
