Very interesting! Everywhere I rang, they said the comps would be a no go. Did you have the comps on before or after the conversion?

3 different gas systems! do they sill give u the 3000$ rebate everytime? rofl

Well i have been told that 4480s don't fit on if you have LPG and that 4499s were the go, but not sure since anything can be modified to fit

Prices do vary from store to store. At majority of the stores I called, I got quoted $430 for just the extractors. After I rang around i managed to score myself brand new pacies 4480s for $400 including new bolts, gasket and also one flange so i can weld it onto my hi flow. It pays to call around and getting prices.

Since 4480s cost about 430...I would think the 4499s would cost a little less...maybe in the 350 - 400, but not too sure.

good luck with it.

phong =P~

just becareful with using a heat shield. will void warranty on headers and as i understand, will lead to a shorter life span of the extractors

I run the 4499;s on my factory EGAS AU ute ... it was close to the converter ... but had the factory heatshield modified to cover it ... no issues with it at all.

great info........1 more thing, does the cat need to be cut back or is it straight bolt on?
