This is the response I got from Magnaflow Tech Support......

Sir,

We do not give out our CFM numbers because there is no set standard. All of our converters are about 40% better than stock. Thank you for contacting Magnaflow Exhaust Systems.

Dunno where these other companies are getting there CFM rates for these converters from.

Ive sent them another email advising that this company: http://www.nahux.com/NPOWER/product.php?part_no=54309M

advertises that this cat flow 408 CFM. See what they reckon.

Its like beating my head up against a wall.... I gave them the link to that other company who said it flows 408 cfm, and I advised them of the vehicle its being fitted to and said I hope it flows 40% better then the stock XR6 Turbo cat. This is there response.....

Brad,

Please let me know if you have any more questions? Thank you

rriiightttt, sounds like a case of "file it in the too hard basket"

yep, waste of time......

I wouldnt bother fitting it up. Put it back up on ebay......there are plenty of cars it would serve as a good upgrade for, an XR6T isnt one of them

Yeah, would probably go well on a N/A car. I cant see how they can justify there cats flow 40% better then stock when they dont even know what a XR6 Turbo is.... So how do they know there cat flows 40% better then an unknown.....

Spot on .......just a bullsh*t throw away line from a yank minion.

Pretty sad customer support if you ask me.

I pushed em a bit more. This is the best they could come up with.

We do not give out the CFM numbers. All of our cats flow around 40% better than stock all of our cats are high flow having 400 cells per square inch. Our metallic cats have 300 per square inch. Allowing for a higher flowing rate, thank you for contacting Magnaflow and please let me know if there are any more questions.

Im not intending on changing the dump pipe. Wouldnt be able to find one up here anyways....

But I think that if I use this http://justjap.com/store/product.php?produ...=275&page=1

It should work ok with the stock system? It flows as much as the stock system anyway.

Have you had your wastegate ported? that's a good time. Mines auto, all I care about is beating my mates Monaro.

Nah wastegate, actuator, valve springs are all factory BA specs..unmodified. I gave Youngy (the power factory) less than an hour to play with it on the dyno and he did very good in that time. The exhaust with catco cat and centre muffler removed seems to be ok for a total of $560 spent!!!
