Nice bro , do you have intakes as well

[@obtrunco]

Not yet. I guess I’m leaving it for last.

How big is the x pipe

[@obtrunco]

Same as the rest. 2.5"

[@torvarrisevans3961]

Hi , did the x pipe made difference in hp

[@obtrunco]

Actually yeah, in conjunction with a catless exhaust. When it was stock it made 272whp and after 290whp and of course now after the tune it's 307whp .
