Hi all
I've just joined the forum & thoght I'd introduce myself & see if anyone can answer a question re exhaust manifolds.
I'm a Brit based in Germany (near Frankfurt) with an ex military RHD 110 V8, which certainly gets a lot of looks over here.
Anyway, my question is whether anyone can tell me the difference between a 3.5 & a 3.9 exhaust manifold, I've been recommended to replace the current one with a 3.9 as they have a bigger diameter & are therefore much more efficient & will dramatically improve performance. So before I go on the hunt for a pair I wondered if anyone can a. confirm this & b. has had experience of this.
Many thanks
