Less than what I paid.

I bought these - no cat no muffler hook these right up the turbos!!

No CEL light with those? Where is the 2nd o2 sensor.?

I also have the AWE muffler and cat bypasses
They have provisions for the pre cat O2 sensors
The post O2 sensors are left "hanging" to fresh air, you do this to complete the pre cat to post cat readings, you do not remove them
The ECU will adjust accordingly
To date, no CEL light

BTW, I also have my engine tray cover removed to aid in engine cooling and to prevent excessive heat buildup/readings

Wow.. Great.

But the only hard part now is getting your hands on a set of AWEs

AWE seems to be concentrating more on the 996/997 then the 993

Do the muffler bypass pipes hook on to the end of the cat bypass pipes?

IamSMC

Hee hee hee......

If you're asking about the AWEs bypasses, you remove the mufflers and cats. The AWEs bypasses bolt directly to the turbos.

With Fabspeed and similar, you retain the cats and bolt the muffler bypasses to the cats.

The AWE muff/cat bypass design are different from the Fabspeed muff (only) bypass design.

AWEs design is supposedly designed after the same design by Porsche Motorsports.

And the Porsche Motorsports ones are supposedly $3k+.

So there are no muffler tips that stick out from under the back of the car, like the normal look with mufflers on the car?

When you bolt the AWE pipes on the design is so they fit and exit right where the stock cutouts are. The look is exactly like the Porsche Motorsport GT2 EVO Pipes - just costs less but the fabrication is excellent (they even ingraved my name next to the serial #) The AWE pipes are loud and perform better with K24's or hybrids. I have K16's and they are great on the track!!!!! (A bit too obnoxiuos for street use)

So you notice a big improvement in performance when you put these on?

I have the Evo pipes and the improvement is huge. They may be for sale since the car is.
