Schnell Headers on 986 with Stock Exhaust

[rule1]

I have maxspeeds headers on my 2000 and I have had no CEL or any problems with these headers. I had big gains with headers, muffler and EVO intake. Look on his EBAY store, My dyno results on there.

Rule 1

I didn't see any dyno charts on the ebay store. Maybe I just missed it? It did say their opinion was 10-15 HP gain, but who knows really...

Did you go with the Maxspeed exhaust also? I have a B&B and like it so far.

Do you have the chart you can post along with sound clips, etc? I'd love to hear the sound difference.

I'm wondering if you can extend the O2 sensors that were in the cats and have 4 O2 sensors after the secondary cats thereby tricking the O2 sensors not to throw a code?

I will update if I get anything from my local mechanic.

Hey Edevlin-

What brand did you go with for your system and have you had any issues?

This might be an issue of US versus non-US cars. I have a 2001 S and replaced my headers with stainless Cargraphic ones. There are definately only two cats and O2 sensors on my car and the header dos not have the pre-cat pictured in the other post. It looked the same as panameras. I still have the old headers at the back of the garage and will post a picture later tonight.

[panameras]

you are right noone986s, I just fond out that US and North American 2.7 and 3.2 has 4 cat. but ROW has only 2 near the muffler. Im from Australia btw.

see bottom half of the picture, just manifold pipes no cat! sorry about the angle cant get my camera under there without jacking it up.



I guess thats a bonus for us since we dont have to go through the trouble of relocating the oxygen sensors!

so what do you think of these
