Hi,Has any one hollowed out both cats on a 20v
Nice one! How did you do the downpipe one, just out of interest?That's the 2 cats hollowed out about 2 hours work my Alfa booked in for it's mot on Monday and have a 100 mile drive. will let you all know the results.I am will be happy to get an extra 10 bhp 25 would be nice as then I would have 200 bhp we can al dream.
ooh now thats food for thought next time i've got it offA couple of bent chisels and some patience. Definitely no need to cut the precat open.
Does any one have any idea how much extra power I have gained.
