It really depends on where the downpipe ends. I would assume no, but all a test pipe is, is a straight metal tube. I am sure you can make it fit :)

If it's a stock replacement testpipe, then yes it will fit. The test pipe only replaces the Cat... the cat is in exactly the same place, with exactly the same bolts on all hardtop FWD 2G's. The only major difference in the two exhausts is the downpipe on a turbo car.

im gonna say no. i sold a turbo guy my stock cat for emissions and one of their flanges is turned to a different angle. if the test pipe has a moveable flange(might not make sense, but the test pipe i put on my friends 3S had one...) then it will work.

yep. I'm that guy. the flanges for the 4G are straight but the front flange on the 420 cat is at an angle. Other than that, they are the same size, length, shape...

Worst case scenario if the flange is at a different angle, you just take it to an exhaust shop / welder and have them change the angle. Should take all of 10 minutes.
