Other than the exhaust, not much. I have some Mishimoto silicone inlet hoses, and K&N airfilters in the stock airboxes. My car was already tuned before I got it, as you can see in the graph. Thanks to the exhaust, the extra 17HP were extended to an extra 48HP over stock. I spent some thought over the exhaust. The performance gain was not my main reason, but I simply did not want to have any rust, ever again!
The pictures in my start post shows the cats at fabrication time, but also part of the "stainless" pipes of the custom exhaust that was fitted when I bought the car. It looks horribly corroded. I did the ceramic coating due to the fact that there were no heat shields on the aftermarket headers, but I decided to coat the whole exhaust after I got a good price for it to be done. Nevertheless, the whole setup costed a pretty penny.
