FWIW, you need to email them directly.

Charles forgive me if this was asked recently and I failed to see it, but what kind of feedback have you gotten (if any) from Turboxs exhaust owners looking to tone down their exhaust a bit?

I refuse to go back to a sub 3" system but have to admit in my ever lessening youth the straight up turboxs system is a smidge on the loud side.

I was wondering the same too .... what happened to that option :(

I would buy a 3" silencer or high flow cat and have an exhaust shop weld it in for you.

The turboxs mid pipe has a resonator in it already but I don't think its accomplishing much of anything. Perhaps the solution is adding the BHR resonator to the front... hmm...

dlin1230 09-10-2011 11:31 PM

its resonated right? will it be able to spit fire?

bse50 09-11-2011 02:35 AM

yes, yes

If one wishes to be an exhaust-flow purist, CoastFab has/had a great explanation (hat-tip to TeamRX8 for providing a link somewhere around here) about what happens regarding exhaust flow properties when the louvered resonators lose their packing. The louvers cause turbulence which is said to decrease exhaust flow, making an empty louvered resonator flow worse than one which retains it's internal packing. As regards exhaust tone on the Renesis, straight-through resonators don't provide much effective sound damping, even when new.

I need to figure out something soon. I can only assume at this point the turboxs pipe's resonator is a "straight-through".

I must say Matt, that was a fine show from your 8. One of the best I've seen.

PearlStorm 09-12-2011 10:20 PM

Saw my first flame from my 8 tonight in my driver side mirror.... I love it, The sound of the bhr pipe on a straight piped 8 sounds evil ;) Had a guy in a mustang gt give me a thumbs up and ask how many cylinders lmao

I have you to thank for that great video sir. If it wasn't for you that flamey moment would have been lost to history. :bowdown:


edit: the other video was running a map Jeff named "Flamey McFlamerton". The video shot from straight behind was all thanks to Erik and running a regular driving map.

Just checking ot make sure before I order. When I install the midpipe I will get a engine check light? To turn it off I will need a module. Is that correct? Thanks

One last thing is the second o2 bung needed?

I had to bend the hanger on my midpipe because it was rubbing and making an obnoxious squeak. All better now. :)

J8635621 09-28-2011 12:35 PM

Mrkrusedc - eventually, exactly, and it's for aftermarket O2 sensor so only if you plan on getting that or want an easier sell later on.

RIWWP 09-28-2011 01:26 PM

Just because J gets annoyed when I get wordy....


mkrusedc:
You MAY get a CEL with a midpipe. Not every 8 does. Some get it instantly, some never get it, and some get it intermittantly. There has never been a determined cause. Don't be surprised if you land on one of these 3 options. They are all "normal".
If you want to permanently block it, and never have it show up (even if it isn't being triggered anyway), you have to get an AccessPORT from Mazdamaniac.com (he is the only vendor for them now, the only sales outlet for COBB's RX-8 variant of the AP)

The AccessPORT is just a tool, but it is quite a varied and useful tool.

The 2nd O2 bung option is entirely for people that want to run another O2 sensor, typically a wideband O2 sensor. If you are looking to add a 3rd O2 sensor to your 8 (it already has 2, and even swapping the pipe you still have 2), then add that O2 sensor bung. The rear O2 on the stock cat has a bung for it on the pipe by default. That option is just for a 2nd one.

J8635621 09-28-2011 05:13 PM

I'd say the people that "never" get a CEL just didn't wait long enough.

mkrusedc 09-29-2011 04:07 PM

Thanks for the info! Ordering tonight!

people who think spitting fire is cool need to have their car burn to the ground, then they won't think so anymore

At least it's behind the car and not under the car like one of the kids that joined a ways back. Wanted an exhaust dump from the header.... :uhh:

only time it ever shoots fire is on the dyno, at least in my car. I enjoy the sound and assume most people get a mid pipe for the sound. I've yet to figure out a way for a drive to see the flames coming out of his own car while driving it.

but, as with all things, everyone's car is their own. What they like and why they like it is up to them, F everyone else

About 4000 miles of highway driving and two autocross events.

09 r3 with 33k miles on it. Only drivetrain mods are the BHR ignition and rb intake, both of which I installed with the midpipe (new plugs as well).

Was merging onto a highway on my way to work and noticed that the power completely died at about 7k. CEL came on shortly after - p0420. Pulled the midpipe off when I got home and the cat was as seen in the picture. Chunks of the cat were pressed up against the O2 sensor.

Seems like it should've lasted a lot longer than that.
