Was wondering if any of you kind chaps could help me Which exhaust system is better for getting the most performance on a s4 b5.?

Is a 3" system better than a 2 x 2.5" system? Sorry if this has been asked before, i dont seem to be able to get a definitive answer

Cheers

If your talking miltek then i think the 2 x 2.5 system gives you better performance depending on your mods and map etc.... Although i have the 3" single and with all else considered i'm running approx 340 - 345bhp i also have full de-cat aswell.

Thanks for that. Is there such thing as a Twin 3" system? Might be the answer for high power applications
