Hi all, I have purchased a new 2021 A5 45 TFSI 2.0 Quattro Coupe. I’m looking to add a couple of modifications to improve sound and performance and looking for best advice on this model and where to purchase the parts.

I’ve made a list of what I’ve looked at doing and what I’ve found so far.

Intercooler
- Wagner Competition intercooler


Chassis bracing
- Racingline Front upper brace (all I’ve found so far)

Intake
  • Integrated engineering Cold air intake
  • AWE Airgate

Exhaust
  • Army trip Valvetronic (needs S style diffuser)
  • Supersprint (has options for OEM diffuser but no demo videos)

Tune
  • DMS Automotive
  • Revo
  • Evolve technik
is there tune options that won’t bring up the warranty fault in ECU?

Brakes
?

Steering wheel (thicker and flat bottom)
- Euroactive retrofits

the main things im looking to get out of it are
  • more sportier sound and some exhaust noise
  • increase throttle and power response
  • keep the engine cool for those long highway drives in summer

Hello mate and welcome on board!!!! In my opinion you really need to get some miles on the car so that the engine loosens up before you start with your mods. Your list sounds very comprehensive!!!

You've done a pretty good search so far my dude, I also just purchased a 2021 A5 45 Sportback, and will be doing some of those similar mods but not too intensive to void my 5 year warranty. Ill be following this post for more info and if you find parts please post them, as will I.
