Exhaust help

[No 1]

I'm just about to swap my 3.5 for a 4.6 and as part of the swap, I want to pop a new exhaust on it. I've found a stainless steel system complete with tubular manifold, but it's for a 3.5.

Can anyone advise if the fact that my engine is 1.1 litres bigger than the engine the exhaust is tuned for will have a detrimental affect on its performance?

Alternatively, can anyone suggest a supplier that offers tubular manifold exhaust systems for Land Rovers. I like the idea of sports stainless, but it's not essential.

Thanks in advance.

Hello,
Used such a system on a 4.6 V8 in a Bowler Tomcat 100 race car. We finished 9th in the French Tout terrain championship and won our class and group iun 2003 so - not a problem. Also too big a bore "header" will have a detrimental effect on torque at lower engine speeds. The racer had four into one "headers" and a 2.5" system from the "Y" piece to the exit. silencers were absoprion muffler type. The engine made arounf 200 to 240bhp on the rolling road at Cheltenham.

hope that helps,
Matt

A mate has a Janspeed fitted to his 4.2 in a Range rover Classic. Might be a good starting point.

I used Rimmer Bros in the past. Good advice & great products. Give them a call.

AFAIK you should be OK, I can't see any reason not to use it, but as mentioned in the previous posts you will not be running an OPTIMISED setup, but I'm sure you will notice a difference anyway...
