Anyone had any experience of such? As far as I can see, it's the only UK exhaust with a high flow cat. (although correct me if I am wrong).

I like the idea of having a cat retained, but without killing the power, and wonder if this device is any good in comparison with the full decats?

 

Seems to work pretty well - they claim the earth, of course, but Steven Done (EcuTek guru) uses one & his car seems to go OK...

 

Have a look at the Aussie made APS High output exhaust thread in Members gallery. JW Racing stock them in this country. I had one on my STi5. They retain the cat. and are fully emmisions legal.

Graham Goode also do CAT exhausts, and they too claim the best..

 

Thanks guys.

V5 - the APS system certainly looks very nice on the web site. .

What was your opinion re:noise / performance? Looks like a lack of 2.5" joints which must be a benefit for performance, I guess? Is it louder and/or better sounding than say a prodrive or scoobysport system?
