What is the difference between the competion Pacemaker extractors and the tri-y Pacemaker extractors if any? One part number that seems to keep getting mentioned is PH4001. The website is a little confusing. From what i gather tri-y are the competion headers and tuned length are the 4 inot1 design. Am i right?

tri-y are 4-2-1, tuned are 4-1 i have try-y's in my v8 xe. im told that tri y are better for low down torque and tuned are better for top end power.

The tri-y design gives the best all round performance. 4 to 1 does give more up high but aren't great down low and through the mid-range so they are generally used on the stroker engines which have tons of torque anyway. Pacemaker is not running 'competition series' any more, just tri-y and tuned length (4 into 1) series.

from all i have read on here and heard around the traps don't use pacemakers go for hurricane headers.

Don't know who you have been talking to but the majority of forum members have pacemakers. Harricane's are still good headers and cost less than the pacemakers but IMO pacemakers are bewtter quality and performance.

Pacemaker comp's on my ute

Comps are better for High range VS TriY for low range

Hurricanes were developed by Liverpool Exhaust - it is their own design. From all the results I have seen/heard, they outperform Pacemakers hands down. Pacemakers are still a great header and will do the job though - far better than stock, and probably next best performer to the Hurricanes. And they are more accessible by non-Sydney based people.

The pacemakers for E-series V8's are PH4000, I got mine for $495.
