2014 S5 mods exhaust/air cleaner/pulley/tune expected COST and options
 

Hello,

I am looking to do a "few mods" top a 2014 S5 yet do NOT want to BLOW IT UP! Looking to do the air box and common AEW is it exhaust touring with NON resonating pipes (NOT so loud/droney) plus pulley/tune upgrade. QUESTIONS as I know options exist: I do NOT want to do anything to blow it up but am told the 450+ RWHP it should make when done is harmless??

What options on parts might anyone suggest and will it truly make 450/480 rwhp out of my year car?? EXPECTED TURN KEY cost including labor from most known shops to do these upgrades?

ANY major worries IF I need reg scheduled maint done under factory warranty just take it in to get tune changed around prior?? They tell me they can do.

Like an idea of cost I should expect to pay to get these things done! Cant believe that pulley/belt is $800ish wow! Exhaust $2300ish. BUT TUNE and pulley installed/tuned expect what??

Thanks when able............like to know turn key parts/cost if able and realistic rwhp gains? Also to confirm/deny these basic bolt ons will NOT lead to major mechanical head aches!

Can do all this without changing to bigger inter cooler bigger injectors blah blah blah!

Thanks when able.
