Im looking for new extractors lately, the 4480 in particular, i have found a second hand set and from the pictures of them the pacemaker badge is on the 4th prim pipe, been looking at forum members pics of them with the badge on the 5th primary pipe,
Just wondering was there a design change? i have been told that they used to have 38mm primaries then they changed to 41mm is that right? im getting the guy to measure em for me. |

Totally Agree! I actually would prefer a set of the old comps with 38mm primaries, alot better for street driving. How often are you bouncing off the rev limiter. Small primaries equal faster exhaust gas velocity, also better power in the low rev range. Cheers...

i like my newer 4480's considering, 4.11's 3500-6500 cam, it spends alot of time up in the high revs

I reckon you can find a better deal. If I remember correctly I paid maybe $400 for a new set with new bolds, gasket and a spare flange to match. phong =P~

who ever made the exhaust ports the same size as the exhaust valve, needs to be shot. or at least his hands cut off so he can't ruin any more heads |

I believe it has something to do with pressure. More exhaust flow outwards but not enough back pressure for low down torque, unless you have your foot on the floor all the time or forced induction. Slower exhaust coming out or something. Think of it this way...when you blow your nose, it is easier when you squeeze one side and blow one then the other, where as if you have both your noses open the blowing is much slower and less effective. Thus if you want more exhaust flow coming out of your car, slightly smaller primaries would be a good thing... In saying that, I could also be talking s**t. phong =P~ EDIT: My wording isn't also correct....so maybe someone else will elaborate or link us to a thread somewhere in FM which I am sure someone else had started previously.
