Extractors or cat-back pipe first?
Hey all... Once I have all this debt paid off I'm think of doing the exhaust on the bovine. Firstly I want to know if it is better to get the cat-back pipe changed to a larger diameter pipe, say 2.5" with muffler and all that stuff, or just get the extractors and bolt them on without the pipe? The reason I am asking this is because I'm impatient and can't be bothered waiting twice as long to get the complete system all at once.
How much performace gain is there from doing the cat back exhaust? Is the stock cat back exhaust good enough to bolt extractors to?
This has probably been discussed before, so I apologise.
