how much would this help?

[polan]

hi guys was wandering if i decide to get this if i will fill the difference and if it will make a small or bigger difference between the 3 things i wanted to do i was going to start off getting (1) a duplex system from cat to back then to (2) decat then was going for (3) a manifold

[mallboy]

depends what you are looking for, for sound or performance?

a manifold and exhaust system would be the best for sound but for performance a manifold and decat exhaust system will be the best

[polan]

well powerflow/longlife will be putting there own on and they say they make them for both sound and performance

[Josh_Phipps]

Powerflow aint the best people to go to for performance mate.

[bullit]

if you want performance pooerflow want to be missed. duplex i guess your meaning 2 tail pipes when you really want one

so a decent induction, manifold and system on vts your looking at 10-15 bhp give or take. not the bhp that the products claim they give

[polan]

well i got a green cotton induction kit atm first thing i was going to get done is a duplex system tailpipe at each end and to decat it then doing manifold seperatly

green cotton. open kit then? firstly i personally would remove this and get an enclosed system.

for performance id personally say avoid pooerflow at all costs.

get the fannymould sorted with the exhaust it will save alot of ballache, get something like a gmc 4-1 or a raceland 4-2-1 from kam racing on here.

duplex systems are not the best for performance either.

dont get peco either
