This Kooks range gives you X-pipe and H-pipe choices for a matching long tube header setup, with catalyst and pipe-size combinations for the rear exhaust you want to run. The table separates the header inlet from the rear outlet so you can choose a system that joins up correctly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSKUs:\u003c\/strong\u003e 11313100, 11313110, 11313120, 11313200, 11313300, 11313400, 11313410, 11313500, 11313600\u003c\/p\u003e\u003ch2\u003eX-pipe or H-pipe\u003c\/h2\u003e\u003cp\u003eAn X-pipe brings the exhaust streams together through a crossover and tends towards a smoother, higher-pitched character. An H-pipe connects the banks with a balance tube and tends towards a deeper, more traditional muscle-car note. Your mufflers and catalysts still affect the result, so choose by the complete exhaust sound you prefer.\u003c\/p\u003e\u003ch2\u003eMatch both ends of the pipe\u003c\/h2\u003e\u003cp\u003eThe inlet must match the collector size of your Kooks headers. The 2-1\/2\" rear-outlet versions connect to the compatible OEM rear exhaust and reuse its clamps, which are not included. The full 3\" rear-outlet option needs a matching 3\" aftermarket rear exhaust. A 3\" inlet with a 2-1\/2\" outlet is a reducer arrangement, not a full 3\" exhaust.\u003c\/p\u003e\u003ch2\u003eChoose the catalyst for your engine\u003c\/h2\u003e\u003cp\u003ePerformance Cats are for naturally aspirated engines below 550 RWHP. GREEN catalysts support naturally aspirated or forced-induction applications within their rating. Competition Only versions use catalyst-free pipes for competition, off-road and track use.

The relevant pipe clamps are supplied, while the 2-1\/2\" OEM rear clamps are reused.
