No one said these were POS or substandard in any way? Someone made a comment about the price that you didn’t like… that was it. Anyway I look forward to seeing more updates on new 996 parts.

The more products for the 996 the better. Creates opportunity for buyer to choose which one they want. Don't see anything wrong with that. Bring on the competition.

I agree the more new players in the 996 game the better
our cars are more then 20years old and need all the help it can get

I don't see O2 sensor bungs on that. My understanding is that many aftermarket x-pipes put them in awkward locations.

Also I personally don't mind paying a little more for a product that:

• is made from top quality materials
• is made in the USA (this one has been getting more important to me)
• is thoroughly engineered and tested
• actually does what it claims to do

That pipe has the post o2s just after the cat but in the other side so u cant see them. Its basically the stockish version of what i just installed. U have to cross the wires but they reach the o2 plugs. Although u have to pull the plug out of the retainer. Not sure if thats the same as the flat6 version but i cant inmagine they were able to get theirs any closer.

I think I'll buy from the builder for Porsche for all Cup & Motorsports exhausts at a cheaper price. Not a hard decision unless you've drank the kool aid.

I do not think that is advised, I think you have to either extend the wires or relocate the bungs. Pretty sure the post reads temp and will dump fuel to cool the cats, so if you have them crossed it is comparing the wrong bank. For the pre fueling is controlled from the O2 sensors so crossing those could have major implications.

There is no temp readout. Post cat sensors are for efficiency-only. It hardly matters.

I do not think that is true, I think this is a common misconception that all post cat O2 sensors don’t do anything with fueling, but some actually do. I actually had a conversation with SuperSprint who designs a setup for our cars and they were adamant to not cross them and they needed extended. Pre cat and post cat should be connected to the same bank.

That said you are welcome to do what you want. Buy what you want, install how you want, I just don’t want someone to read this and not do more research around crossing them.

On the factory system on the drivers side of car the plugs r precat (black plug) for bank 1 and the post cat for bank 2 (grey plug). Pass side is precat bank 2(black plug) and post cat bank 1(grey plug)

On the cup x-pipe the post cats r on the same side as the precat, so the post cat sensor wire has to go to the opposite side of the car. There is no need to extend the wires or change the harness as it reaches.

There is no reading the pre and post cats from the opposite banks. U will have to do this with any cat-ed x-pipe.

bgoetz

Yes as long as the pre-cat/post-cat are on the same side life is good. So I am not sure why reference was made to crossing the wires because you aren’t crossing the wires. The SuperSprint isn’t a x-pipe and the 2ndary is far downstream, other cross over designs are similar. In this case you cannot cross the wires.

I guess you also use Mobil 1.
It’s the official oil of Porsche Motorsports.

I do, but mostly because I came into $1200 worth of free M1. I would still probably use it anyway seeing as my motor could probably run on crushed rocks and still outlive the average M96.0

I hadn't thought of it, The cross pipe setup is lighter than the factory cats+pipes using the bicepterometer.. I'll see if I can do that I hope to have them on in the next day or so. Shipping weight on the cross pipe IIRC was 22lbs..

Good idea I have a sound meter on my IPHONE, not a fancy one but should give a decent relative Comparison.
