AP-X OBDII resonated test pipes and Hi-Flow cats

[angus]

I currently have one set resonated test pipes and one set 100 cell cats ready to go for '95-'97 cars.

Got my RTPs in, can't believe how much better it sounds on the GTLW coming from normal test pipes, absolutely ZERO rasp, even on decel.

Two thumbs way up. I'll try to get a vid of it this weekend.

I am very happy that it fixed your rasp problem.

In the immortal words of John "Hannibal" Smith:

"I love it when a plan comes together."

I have both test pipes (resonated and non) and 100cell cats in stock now!

Any updates on 00-05?

I am currently working on jigging them, it is taking longer due to all of the orders for 91-94 and 95-99 pipes!

I am working on a run of 91-94 and 95-99 pipes (resonated and non) so that I will have them on the shelf for immediate delivery.

what happened to the pictures?

Sorry guys, here are the pics!

Look like 02 headers to fit 91 and up exhaust?

Those are for 95-99, they can also be used to adapt 95-99 headers to 91-94 exhaust.

The second picture?

All the pictures, this thread is for '95-'99 test pipes - these are made so that you can use them on any year NSX with '95-'99 headers and 91-94 exhaust - they incorporate the adapters that are necessary to adapt your exhaust, simplifying install and saving you both money and weight.

The 91-94 test pipes are here:

My 00-05 test pipes are still in the works, they will be ready as soon as I can finish them.

What is quieter? the resonated pipes or the cats? Will these cats pass smog without any tricks on the 02 sensors? will they not throw a CEL? What is the difference between 100 and 300 cel?

The cats are quieter, the resonated test pipes are not much quieter than a straight pipe, yet do not have the rasp associated with straight pipes.

Neither of the cats will cause a CEL and they will both pass smog (our test locally is the same test used in cali) - the 300 cell will "clean" slightly better and be a little quieter than the 100 cell. Also the 300 cell is a ceramic core, while the 100 cell is a metallic core.

Thanks. Do you have weights on the cats? what's the benefit of ceramic versus metallic. Sounds like the ceramic is lighter.

I haven't weighed them but the metallic are lighter, they are both VERY light.

Once mine come in I will make a before and after video. I've got DC headers with TPs and a GTLW right now and low RPM rasp is pretty ugly.

Did you ever post a vid?

No I've been dragging my feet on it, if the weather is good this weekend I'll try to make one.

Finally got the video made, sorry it took so long. :redface:

For comparison here it is before the resonated test pipes.

Excellent video! The resonated test pipes really cleaned up the sound.

Thanks for posting the vid!

 

[e.pie]

Yes they did, still a really happy customer.

I'd love to hear what these would do to the sound on a GT-One 5.1 or Pride.

Very interested in the 2000-2005 applications! I got a 2003 exhaust in need of some of these. Any updates?

+1 (if there was a plug/play application for my 2004 NSX with no CEL then I'm a player too)

Coming soon guys! I am still perfecting the fitment.
