vs clubsport exhaust system question

[mr_clubby96]

hey guys i own a vs clubby 5 speed im after a decent system thats not gonna loose power putting it on im running a basic 2.5inch single system with stock cat and centre muffler with a sports muffler on the rear also running set of pacemaker headers

just deciding on wat do go for in size n diameters twin or single

the motors has been rebuilt with 10.5.1 comp flat tops forged pistons im running the biggest cam for the 308 engine and also alloy puush rods and harden springs

fuel setup been done also and running filter with a quad throttles

just not sure wat to go for

i called afew places up few ppl where like saying go with a single mandrel 3inch with high flow 3inch stainless cat centre muffler and rear resi with a dump tip

and some say go with twin 2.5 full system including xpipe twin cats and twin straight threw

any ideas wat i should be looking at for??

could be wrong but i always thought a 2'5 inch was recommended cause larger ones lose power

i was gonna go twin 2.5inch with twin cats but exhaust fellow said 3inch single would run alot better on a 5l with 3inch high flow cat
