I got the TBE for my STi. I like it a lot, sound and fitment is A+, but i would make this note:
At first, i used four stock length kb hangers, but they only leave about .5 inch between the muffler and bumper. This was not to my taste.
Then, when i went to change them out for the kartboy long hangers, i found that the muffler had shifted and was actualyl pushing up against the rear stock length links. when i took the two rearmost off, it sprang up. When i got them all off, it quit this weird behavior. The longer links retain a stock distance between muffler and bumper, and improve the angle of connection of the donut gasket.
