Exhaust Diameter V's BHP
WHats a 2.5" diameter exhaust good for power wise before needing to go to 3"?
In contact with the new owner of my old ST and turns out my drunken eBay purchase was a 2.5" cat back not 3".
Plans are for a 3" down pipe as he just fitted a 3" decat. Is there any need for the cat back to be binned off for a 3"?
Thanks, Carl.
