I can't believe this thread is still alive!

I just picked up my 3rd RX-8 today. What exhaust will it be getting? Yup, you guessed it...OBX.

 

Did OBX ever fix the hanger length issue? kinda looking at this now.

couple of sound questions
At idle would you rate:
it almost as quite as stock to wake up everyone in a 1 mile radius?

On highway, cruising speed (say 65, 2500rpms) does it drone? if so, like headache inducing drone?

WOT, sound: Deep growl to weed wacker?

Over all, is this someone that people are going to hear from miles away?

is this the same one people are purchasing?

anyone figure out what the difference between the R and non-R?

 

hmmm. I guess I'll pick it up, I want a new sound but I can't afford 650+ dollars for something. least from videos doesn't sound raspy/farty/lawn appliance like. I suspect it is quitier than the TurboXS which is the next cheapest option. Hope it doens't have hanger length issues.... really don't want to deal with that.

I think I see the difference between the R and non R, there is also a clamped version which looks like it crimped folds and not welds....

 

If you haven't already installed it, would you mind terribly getting the dimensions of the anti-resonance can and the pipe stud leading to it? Lengths + diameters? I'm think if there's room somewhere in the SP2, adding a similar can might help with the 4k rpm drone. TIA!

 

I'd suggest the BHR resonator which will also serve to muffle as well. Any 3" non-resonator pipe is an evil beast.

 

It was installed last year.

There is no difference in the R and non-R. And no the hanger issue is still there.

 

/Resurrected

I just bought the OBX Racing Catback and installed it today. Welds were great, everything fit right together.

The sound is very elegant, it's not ricey at all which is what I was afraid of the most. There is no drone. The sound is not very loud at all and will not get the attention of cops. I'd say about 1.5x stock exhaust, but much deeper and raspier.

I'll post some clips and pics tomorrow. Overall I am satisfied for sure.

 

I'm really interested in hearing it. All the old links don't work for me. Also, do you have a link to the eBay post you bought it from. Maybe the sellers name as well.

That is where I bought mine from, it came with the gasket needed, i just re used the old nuts.
The hanger on the right side is slightly off now that i look at it, but i can fix it easily tomorrow.

 

I had to grind off about 1/8" around the bolt holes on the flange to get it to fit. Other than that, no complaints with it.
