Chris32, If the dump pipe has a divider that protrudes past the dump flange, it will hit the built in turbo one. Otherwise, what ever dump fits a stock turbo will fit yours. Personally id hunt down the original spec dump that was available with the gt2535. Pics of it below. http://www.sau.com.au/forums/topic/202920-hks-gt2530-dump-pipe-recommendations/
