The cat back system starts from 60mm off the cat and then split to 50mm dual back. You can expect up to 7% in hp. As far as noise the sound is mellow, not loud of obtrusive.



This image is an old one, but the newer systems have removable tips.



In addition we also carry high flow cat. These cats units are HJS 200 cell cats and would trigger any CEL.



Let me know if you have any questions. You can reach me or anyone by calling us 1866-533-1777

Cheers!
