exhausts: xf v el

prior to owning my el I owned an xf (4.1) with 2.25 inch zorst and extractors and it went very hard for a 350,000km engine eg sideways on take off and spinning into second gear. My question is, why is a slightly smaller engine 4l (el) need a bigger zorst (2.5in) for optimum performance?

Probably because its a more efficient engine and as such will pump more exhaust, despite being about 80cc smaller

I went from the standard 2.25" to a 2 1/2" exhaust on my old EA, apart from the note difference, i felt like it was breathing much better, felt much better to drive to. Keep in mind the new exhaust is mandrel bent, and probably sounding tough just made it feel better :)

Re: exhausts: xf v el

So what would give me more power from my 4.1 XF, a 2.25" or a 2.5"?

Re: exhausts: xf v el

Be best to go for a 2.25" so you don't loose power in the lower parts of the rev range...
