400 Series Stainless Steel Body
EPA Rated 6.2L/6000lbs
49 State Legal (Not Legal In California)

They can be had for around $150 per pair.

I'm 99% sure those are the ones I was looking at. Are you sure they're 200-cell though, 'cuz I can't find anything on Magnaflow's site stating that & when I looked at one at my exhaust shop, they looked like 300-cell (?).

Doesn't American racing have their own hi-flo cats aswell? and i believe they are 200 cell as well

I haven't tuned mine for WOT yet but it is tuned up to 7200 Hz on the MAF (I won the xs power system back in Jan) but the part throttle is amazing, the car woke the hell up in the midrange and top end with this exhaust.

I like mine much better now. The exhaust is the perfect one IMHO not to loud with good idle and sounds like a bat out of hell when your on it.

I found a couple on Ebay:

I need a set before I install my system.

Spoke to Rich at Magnaflow and he confirmed that they are 200 CPS cell per square inch!

Intently listening; really wanna take advantage of the xs low sale price but worried about being catless as well. The sound clips of the installed system sounds so mean!!

I vote to for sure run a high flow cat. It is easier to tune im told. I can also speak from experience that it sounds wayyyy better. Less drone, not as raspy. There is also no hp difference in anything under 500RWHP.

greenmachinedriver · 04-17-2011, 09:05 PM

i installed magnaflow cats on mine yesterday it did not change the sound much but it did tone it down a little and took a little rasp out of it.

Tshepp · 04-17-2011, 09:48 PM

Did you have to get them custom welded in-line with the XS system? I am leaning towards having cats put in when my system is originally installed.

greenmachinedriver · 04-17-2011, 10:19 PM

Yes I took it to a localexhaust shop and got them welded in.
