But as time is going on im getting the urge for POWERRRRR! you know how it is!!
The standard cat back isn't that restrictive - change the downpipe and get a 100/200 cell sports cat if you're just after extra power.
You could also de-resonate your standard exhaust by cutting out the middle silencer and welding in a straight pipe - that makes it a bit louder without the need to change the whole thing.
