Already have a twin 2.5" cat-back pacemaker exhaust which I love the sound of. Am I right in saying the standard system is 2.5"??? so obviously where the pacemaker merges and bolts up would be a restriction and need to be cut out. So how then do I split from a 4" to twin 2.5"? Are there pre-fabbed adapters? or will it be a costly custom job? Throw some dump/cat combos at me. Link to comment Share on other sites More sharing options...

There's a 4" dump and that that bolts to factory exhaust here. http://www.seperformance.com.au/exhaust_systems.html You'll probably still have to get the waste gate port and flapper mod done.

Getting CMS to do the wastegate, flapper mod and injectors with the tune around 330kw. Aiming up to 450kw in the future 1 Link to comment Share on other sites More sharing options...
