hey guys got a question for those of u that are turbo. i drive my turbo rx8 daily just wondering if any of u would recommend that i run a mid pipe & is it insainly loud. the reason im asking is that i also have a 2 month old baby and i dont want to blow his ears out.

 

I was in the same both as you a while back. The turbo will quiet the sound of the exhaust down a bit. If you can get over the smell of gasoline when you idle the car then you can get a midpipe. Now with that you won't pass emission test.

A quiet midpipe needs to have big resonator or duel resonator. I think with the baby, a single resonator may be good enough as long as you don't hit the gas pedal hard when you drive around with the kid. I have Mazsport duel resonator and it is really nice. Sound as quiet as with stock cat and still loud enough when you hit the gas. No resonance no booming sound. I highly recommend it if you can find a used one.

If you run your car with Cat and turbo, I don't know how long that cat would last because your car run hotter exhaust.

 

think of the polar bears

 

wait for the BHR midpipe. and yes the turbo muffs the sound youll be okay.

 

thanks guy i will go ahead and pick-up a mid pipe. thanks agian.

 

Don't expose your kid to sulfer fumes.

Someones going to report child abuse on you.

You think I'm kidding?

Try spanking your kid in public.

 

Also you may very well trip your Check Engine Light. All this for a few hp. Better off getting the RP Supercat. And the cat acts as a resonator. Smell alone will be enough to make your kid cry.

 

Get a high flow cat and make everyone happy.

 

Well, as long as you or your kid or someone don't stand behind the car. It's all good. I've been running with the midpipe on my 8 for a while now, and on my previous cars too. It doesn't smell that bad when you get used to it.

 

so with the mid pipe you wont pass an e-check, but would an RP supercat pass an e-check?

 

A sniffer won't detect a difference between a regular or hi flow cat. A physical inspection might not pass, but only if the inspection person knows what the stock cat looks like vs. the RP unit. A midpipe will 100% fail a emissions test.

 

alright thanks man cuz im in the market for something to replace my cat with but if the RP might not pass ill just go catless and swap it back in for the e-check.

 

The RP Supercat WILL pass emissions. Like I said, unless the inspection person knows the car well, he won't be able to tell an RP Supercat from a stock cat. Probably 95% of time they won't do a physical inspection anyways.

Your midpipe WILL trip your Check Engine Light, which will be pretty much an automatic redflag & 100% WILL NOT pass the emissions test. You need to get a Cobb Accessport to wipe the code before you go in, if you get the midpipe. Once the CEL is tripped it doesn't turn off unless you disconnect the battery again, re install your stock cat & reconnect the battery again.

 

If he's turbo'ed I doubt he cares about emissions.

 

isnt there a any midpipe available that has a plug in for the O2 sensor to shut that CEL off?

 

The mid-pipes have a bung installed for the O2 sensor, but that sensor checks the efficiency of the cat (which you no longer have with a mid-pipe) and it'll still throw a CEL.
And O2 simulators don't work with our car either.
Only way to mask the CEL for the O2 sensor is with the Cobb AccessPort.

 

well that sucks. i was under the impression that the bung would shut off the CEL because having my CEL on all the time would really suck. and i dont have an accessport.

 

Before I got the AP I ran for a couple years with the CEL on all the time.
Got used to it after awhile.
But yeah, its also good to have available in case another system generates a DTC.

 

so theres absolutely no other way to get that CEL off without the AP? if i do put the midpipe on and then switch my cat back on for an e-check for example, will the CEL still be on?

 

You'll have to clear it, but it'll go away.
I already did this when I got e-checked.
I can show you how at our next meet

 

It will go off in 2 or 3 'drive cycles', or you can reset the computer.

S

 

okay thanks. cuz i was actually looking at getting the AP a while ago but i didnt think i was gonna get enough use out of it to spend 800$ on one.

 

LOL... I understand.
I use mine almost daily to display my MPH.
Where I have it mounted, the display is just to the right of my FOV.
If you look centered between the windshield washer nozzles, that view is where I see the MPH.
I find it easier to look over and back instead of looking down and up (don't ask, I like it).


But honestly if I didn't relocate my OBD-II port to the ashtray, I wouldn't use it daily like I do now.
The cord interfered with the leg and got annoying.
I even tried bending the bracket holding the port, but that didn't help too much either.

 

yeah i heard the location of the OBD-II port is a pain in the *** for some people depending on how you sit. but idk im thinking im gonna end up going with the new RP supercats cuz on another thread i was on they said if i buy the brand new version of it that it passes an e-check and it doesnt have anymore reliability issues. i just wonder if it will change the sound of my exhaust and by how much

 

The Supercat acts as a resonator & will keep the exhaust quite a bit more quiet than a midpipe, especially with the Greddy SE. Sorry, but a midpipe with the Greddy is a ridiculously loud combination. Even with an RP Supercat it will be loud. With a midpie, it's the "get ready for the cops" loud.
