Nameless Performance BRZ Axleback Exhaust

Since FA20Club and Perrin are selling a piece that is EXACTLY like the OEM piece (just bigger diameter) theirs will fit LHD and RHD cars; both their offerings have the OEM bends.

That's a bit of an assumption. There's sometimes weird little differences between RHD and LHD that people don't think of.

First off, is the OEM part actually the same part # for LHD and RHD?

Then does the part being slightly bigger allow for contact of another part that has a different location between the RHD and LHD versions?

Perrin claimed that their exhaust was good for all cars, at first, but some auto guys ended up having rubbing issues that had to be corrected.

It's not an assumption. This are words taken from Nameless posts. They said the weird bend on the OEM overpipe was there to allow RHD steering colum to sit there, and since it was not needed for LHD cars they changed the bend. That is why we need to lift the car 2 inches in order to make Nameless (replaces downpipe/overpipe) to fit in. I never assume stuff. I learn reading from the people in the know

Edit: I'm not the end all be all of knowledge, I CAN be wrong, but I don't spit things out of my mouth unless I read it learned it or know it first hand.

Has the Perrin overpipe been test-fit on an actual RHD car, is what I'm getting at.

It's fine for them to just copy the bends, but if they don't actually 'know' where the steering column goes in RHD cars there is a chance that there will be fitment issues.

They assumed that they had enough clearance for the auto trans cars in their cat-back which proved not to be the case.

You'd have to ask Perrin that. IMHO, if the OEM Overpipe found in our LHD cars has bends specifically to fit RHD steering column, it should be pretty safe to think it fits knowing that there is no other interference in the area.

(I also assume that based on the error made with Auto/Manual transmission they would do their homework before stating the overpipe does fit LHD RHD).

They are still selling a 22mm REAR sway bar for the BRZ, so I wouldn't hold my breath about them doing homework on a not so easy to access RHD car.

Edit: the reason I'm being a bit anal here is that in @sierra 's situation it's a way bigger pain in the ass to correct when we are talking shipping between the US and Australia. Just at the risk of unnecessary downtime I would want to have 100% confidence, not just a 'Yeah, sure.' assurance.

@sierra forget anything I told you, all I posted are assumptions and I'm probably wrong

I'm not saying you are 100% wrong, I'm just saying that there IS a degree of uncertainty no matter what the shops say. Specifically that Perrin already made one assumption that was not correct.

When it arrives I'll ask for confirmation that they have fitted one to a RHD before I start doing mine or paying someone else to do it for me. Which is more likely.

It does make sense, when you looks at that big loop in it compared to the Nameless version, that they decided to make that to fit both.

Thanks for spending so long debating it.
I went from doubt to elation and now back to doubt but a bit less doubt than I started with.

What do you guys think about the Helmholtz Resonator? After talking with Ryan in emails, he suggests to add one if you plan on using a header with the full system because of a frequency that it eliminates. Anyone actually have one on their system? I haven't seen it mentioned very much, and I've read about what it actually does. I know it adds a bit of weight, but if it helps the overall sound with a header on, I'd be all for it.

I still want it loud though.

My understanding that it's not so much about loudness as much as it's about unwanted frequencies (which is what a resonator is for). You'll want it if any kind of drone annoys you; by removing those frequencies you're not hearing, the exhaust sounds more tame. My suggestion is to always get the Helmholtz; who knows what annoying frequencies can show up when you start removing and replacing exhaust parts.

Loudness will come from the axleback mostly. I've got the offset version and it's plenty loud without being annoying. I expect the over/downpipe with Helmholtz to change the tone and volume slightly, but with the offset mufflers and Helmholtz I doubt it will be unmanageable. I'd certainly doubt it'd LOWER the volume when I add the over/downpipe.

Designed correctly, it should just get rid of frequencies that drone. If you want it loud but not drone-y, you'll want properly tuned helmholtz resonators. It's really a no-brainer in my opinion, unless it's designed wrong which with nameless that's not the case.

Think I'll be getting it on my system. Convincing enough as long as it doesn't make it quieter. If it removes annoying frequencies, I'm all for it, especially for header applications.

I'm thinking about getting a helmholtz resonator kit to fit one to my nameless downpipe but they are not sure it will fit for some reason? I can't find any pics to show where they fit it on the overpipe/downpipe LHD combo. I would really appreciate any pics so I can work out where to fit it on mine and if it's viable?

Here's the reply from John. I don't want to hassle him if I can figure it out for myself[with a little bit of help]

The helmholtz resonator cuts out that drone point in the mid range. I can send the kit over to you but I don't know if it would fit, we never tested it with the direct fit downpipe.
