Outer Limits 4x4 Board

Hi There.

I'm thinking of re-doing the exhaust on the bobtail .

It's a standard twin carbied 3.5 L.

I have some extractors I will put on , and the intend to fab the rest up out of mandrels and tube ( just as an exercise really ,for something to do for the experience ).

I was thinking of doing a single 2-1/2 inch or is that a little too big , would I be better off using 2- 1/4 .

Any info would be appreciated .

Cheers

I used a single 2.5" on my 3.5 injV8 and it was excellent. The noise was sweet and I felt like it ran better. I used the standard headers though.

Like Micka, all my rangies got the 2.5", with extractors. Do it.

Well that's good enough for me !

2 1/2 is the go .

Thanks guys

Cheers

Yeah I did a 3" and regretted it - just too much drone.
