ok..
you wanna get a zorst...
so.. you have 2 choices...
zorst 1.. a big tail pipe only.. adds sound... kewl .. and a great look to the car...
zorst 2.. semi straight through system (Good level of back pressure maintained for performance) with big bore tailpipe..
heres the catch..
Z1 is £20
Z2 is £350
both produce the same external effect...
the Z2 offering gives a 2bhp realistic increase throughout the range
which do you buy..... and why
