hi im in the market to buy cattless downpipes....which ones provide the most power and are the loudest....thanks

They're tubes that fit on the turbo and exhaust sides...don't think any are better or worse than another.

Yeah, OK, so some are larger diameter tubes, um, that still plug into smaller diameter tubes for the rest of the exhaust.

So, uh, the best ones are the ones you get for the lowest price.

AR design. 3" all the way back and finally tapers down close to the flange in comparison to others that taper down earlier down the dp.

I run cp-e's non-catted downpipes. Can't beat the cast bellmouth housing to smoothly taper the diameter. The engineering and overall design of these pipes had me floored when I received them. I had to temporarily pull my tune the other day and the car still pulls like a raped-ape with just intake and turbo-back exhaust.

Don't wanna start a flame war, but c'mon, how much engineering can go into a couple of pipes? As long as they fit, you're good to go.

Ar Design hands down. Power, fitment and quality.
Dyno proven here and race proven here.

Nuff said.

GeorgeSmooth · 07-14-2009, 02:59 PM

I am not sure which is better in terms of power but I choose AR as they are for a RHD car and I was comfortable with the vendor I bought them from. The locally manufactured South African pipes are as good power wise but many people report issues with gaskets which is due to non perfect fitment. The downpipe is not something easy to access so I would look at best fitment to call a down pipe the best.

RiXst3r · 07-14-2009, 03:07 PM

We sell AR downpipes because of the rock solid reputation and awesome performance.
