make sure you dont get the spectre plastic coated in chrome crap....that one in the link looks to have to small of angle bend, u would need a 45 degree bend like the bottom pipe in this picture

plus the 3" to 2.5" reducer which you is made by spectre and you can order online at summitracing.com.....now my pipe is from a cheap honda kit that I cut up. Now you would also need to drill a hole for the intake sensor and caulk it in
