Looks like stock catback from the tips, you can also see the stock ic hoses, and tip (turbo inlet pipe). At best its a 225 with just a chip and high end brake and coilover suspension. Dont see to many external res on street cars. Deff worth it to sell those parts on the forums for replacement stock parts + money. Might be more than you would make on the car

 

We are not likely to part out the car. if nothing other than the simple fact of the labor cost to do any part swapping.

I drove the vehicle and it didn't "feel" really fast and as mentioned, the stock IC pipes and exhaust wouldn't let me assume anything in the power dept was done.

as for the stock airbox, I don't know about Audi's, but the Subaru stock air box is a great design and usually the best one to have unless you go to a protune with several supporting mods and/or start changing out the turbo.

 

The stock TT air box is ok.
My comment was more regarding that usually a high flo intake is one of the first performance mods done, and a relatively quick/inexpensive way to gain some extra horsepower. Your quote that the car didn't "feel" fast probably confirms that the upgrades were more suspension/brake related.
Best of luck selling the car.

 

I would hold the cruise cntrl set button(with cruise in on position)and see if the eng. Light flashes(like 15sec I think)to see if it's got an APR chip. It probably has a chip. With that low milage, it is a nice find. Might want to see if there is a tuning shop around you(vw/Audi)that can take a look at it, and tell you what's up.

 

I would buy that car in a heart beat if it were closer. I'm looking for a roadster and after looking online that's like 6 grand worth of brakes and suspension.
