I am looking for a stock sti or aftermarket uppipe and would prefer one that doesn't have a flex in it.
I have a brand new one, think its a TurboXS? Does have a flex built in though in case you are interested.
Still looking? I had originally bought an Invidia catless UP (Comes with new studs o2 sensor bung and no flex pipe) due to the previous owner claiming the car to be stock. After installing the downpipe I noticed a Grimmspeed catless up pipe was already installed. Brand new in the box still. Let me know otherwise i'll return it to MAP one of these days when I have ambition haha
