Mine belonged to a prominent car collector, he made it look like a 355 challenge with seats and wheels, but also included stock parts. I got a small non airbag steering wheel and boss along with a yellow tow hook to add to make it look even more like the challenge
Fabspeed...I have a bit of history with these guys, basically I was lied to by them and found out the headers can be bought for way way less than they sell it for from Taiwan. In the process of ordering some from the Taiwan factory now.
Cats I suppose will be a great mod but I am thinking of decat for a better effect. Last owner put on a back box of some sort that's louder than OE but not by much so a Capristo is definitely on the wish list.
I am using the OE airbox with k&n filters which melt in the heat of the engine bay, I am thinking of either a proper induction kit by gruppe m or doing something like this which should be way cheaper but looks kind of weird (see pic)
I am also thinking of doing a chip upgrade, a local tuner shop has the software to chip the 355 but am wondering if its a stage too far. To be honest it's an old car and compared to a 996gt3 or an Evo that I have the car is not exactly quick, even modified golfs will almost certainly give it a hard run on most roads in HK, so might as well just keep it stock for the moment and just mod to make it more reliable and sound better.
I certainly do need brakes though, thinking of new discs and ferrodo ds2500 pads all round or do a front 6 pot caliper upgrade with bigger floating discs too. Compared to Porsche brakes of the era I think the 355 OEM setup is certifiably inferior.
All that being said I am running the car on a tight budget and have a baby on the way, so I suppose mods will come slowly, first priority is to get it running smoothly and then do some mods.
Hope to see your 355 on the road soon, mine should be in the shop until the end of the month!
