XHXR6 36 Posted September 30, 2014 G'day Everyone, Would anyone know where I could get an off the shelf 2.5'' sports exhaust in Victoria for my XH at a reasonable price ? I've already got a set of pacies 4499's to go on, just after an exhaust and cat now. Share this post Link to post Share on other sites

Outback Jack 6,352 Posted October 1, 2014 I run 2 1/2 pipe on mine, extractors, high flow cat and a muffler. Good flow, 3 would be better with upgrades to motor. The drone is usually due to what muffler you use, or using no resinator. I get it on mine with a redback muffler, my friend doesnt with a glass pack Lukey.
