4" dump to match up with existing twin2.5" exhaust.

[bupalooga]

So I want to put in a 4" dump & cat before I go for a tune. 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.

Stock fg is 3".

There's a 4" dump and that that bolts to factory exhaust here.

You'll probably still have to get the waste gate port and flapper mod done.

Thanks Ozy! hadn't heard of these guys before & they seem to have the parts that I'm looking for.

Getting CMS to do the wastegate, flapper mod and injectors with the tune around 330kw. Aiming up to 450kw in the future

Venom exhaust have the 4'' dump pipe now that matchs up to standard system,.
