hi guys sorry for being a newbie but just a few questions
im currently looking for an exhaust but wanted to know
which is the best top hat to get for my mk5 astra 200bhp
i would prefer one with the dump valve port but have seen a few on ebay and don't know which are best as i would like the hard pipe in between aswell
my car is totaly standard at the min with just a pipercross cone on so looking at starting to get bits and bobs for it
would ideally like around 250bhp or so once i have got all the parts and a remap

thanks guys
scott
