It is because you can't buy them directly from magnaflow, you need to buy them from a dealer, expect in the $800 range, uninstalled

Hmmm... that is strange I wonder why they say now available and in stock? It says they have 49 parts available.

I seen on another website you had posted that you ordered it off the web for $609. What website was that? On justmagnaflow.com they have it listed for $725.

I did get it for $609, however unless you get a discount somewhere you are probably not going to find it online for under 725

Default Magnaflow exhaust for LS4

I spoke to Magnaflow directly. the reason they do not show a price on the website is they have not finished the exhaust yet. they told me by the end of 11/06 it will be offered. you can be put on the waiting list and they will contact you when it is ready (they took my info and said this)

For the Monte or the Imp? I know the only thing different between the two is the tailpipes.

Default Magnaflow exhaust for LS4

I spoke to Magnaflow in October and asked why they list a part # but no price. for the GXP and SS exhausts. They said we should be able to purchase (directly from the website if we want) by the end of November or beginning of December.
