Im interested as well.

I was originally interested and both the items I wanted have never been back in stock. I hope they can open the code for those of us who were on the original list but didn't have the items in stock that we wanted

I'm confused... I thought the cross over version was not available however the website currently shows 19 available???

They had a few crossover pipes in stock early last week, then sold out. But on Friday added 23 or so sets. I tried to order the oversized x-pipe on Friday with the code but it no longer worked, so I opted for the crossover pipes at full price. Still can't get over how fast they shipped and got here! I installed them today. Perfect spot on fitment. Only issue I found was the factory post cat O2 sensor wires were a little short, so I put bank 1 on bank 2s connector and bank 2 on bank 1. Pre cat sensors wires are the perfect length. Also not having studs on the cat pipes makes install a bit tricky with the bumper cover on.


Crossover 200 cell cat pipes - X51 engine with PSE on, I would say it is almost twice as loud compared to factory crossover pipes. It keeps the lower tone rumble. Sounds great and really screams when you get into the upper RPMs. With PSE off, it still sounds great, louder than before but not by much, remains late night neighborhood friendly.


Extremely happy with the purchase. Code or no code it is still a fantastic deal compared to other options out there.

Thanks for the update Ghost.

Did the TopGear unit feel significantly lighter than the factory cat cross over pipe?

*** 3 May 2017 UPDATE ***

Top Gear has agreed to extend the use of the group buy coupon code for a further two weeks. However, after those two weeks, that's it.

I hope everyone has been pleased thus far. I am planning to mount mine this weekend or into next week.

How can I get group buy coupon code?

Ghost_Round

Definitely lighter. Total shipping weight for the TopGear cross over pipes with box/packaging was 13.2 lbs. Pelican shows the factory cats to be 14.5 lbs for the pair.


Waiting for better weather to get some sound clips.

Order placed! coupon discount is now working.

Ordered the cross over version. Coupon worked great and they shipped out DHL next day. Thanks again to "Saaboteur" for the effort/results.

I'm a little confused on this one, haven't had my coffee yet. Can you explain it a bit better? What sensors are swapped where? Any codes?

German888

Me too. Supplier states you must identify 996 or 997 when ordering the cross over version so maybe that was left out and the difference is what caused the mis fit ? Just a guess...

So how much is that in USD including the shipping? And what is the discount code? Thank you

Ghost_Round

Apologies for the confusion. The post catalytic sensors are the issue. When the cross pipes are installed, due to the post cat O2 holes being further down the pipe, the wiring harness on is not long enough to reach the proper plug harness for each respected side. Hopefully the image clears things up. I have not had my coffee yet today, so this may make even less sense

semicycler

Now I understand, thanks. So if you have a failure of one of your post cat O2 sensors the car will see it but report the wrong bank. No big deal, seems like an acceptable solution.

Any chance you could swap the pre-cat sensor connectors too? This way the car's ECU is monitoring each cat with the same pair of pre and post O2 sensors?
