What Exhaust - Twin 45 And Catcam 4900366

[deryck3 1]

As title basicaly.

Will a standard exhaust be ok and not be too restrictive, myn has the split in the down pipe, or would i gain from changing the manifold and system.

Want to get the exhaust sorted before the carbs are set up thats all.

 

the car is used for trackdays only.

 

 

thanks in advance for any help.
