Looking for a original muffler system for a 2013 Scion FRS - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I have a Perrin catback muffler system, I want to go back to the original muffler system. I am located in Charlotte NC willing to pick up. Willing to swap a Perrin exhaust because I’m getting too old for the noise

Don't forget you can also install a stock GR86 exhaust, as those will probably be the more available stock exhaust systems on the used market.

I know the front pipe fits, but does the rest, such as the canister and tips fit?

By canister do you mean muffler? I have a GR86 muffler and midpipe on my 2013 BRZ. I believe the whole system including header and front pipe will bolt up.

Wowzers! Yeah, I meant muffler, it's pretty kool that the whole system will bolt right up. It's gotta be a little larger and probably provides a small HP gain, maybe even a sound difference? How is it working for you?

I recall @Tatsu333 did a FA24 OEM Header change, and power was a bit linear compared to the FA20 OEM Header. There was another user who showed the front pipe diameter between the 1st Gen (Left) vs. the 2nd Gen (Right)

It's working well! The main reason I got it, is 1) that it was more available and guaranteed to be newer than a stock gen 1 muffler but 2) the exhaust enters the muffler from the back instead of the side like on a gen 1 muffler so the exhaust is more likely to come out of both exhaust tips:

Gen 1:

Gen 2:

I doubt I'm getting any sort of power increase having this over a gen 1 muffler.

Some other things of note is that the stock gen 2 exhaust tips are really recessed compared to the stock gen 1 exhaust tips, so I bought the OEM JDM exhaust tips to address this ($100). Also, I've noticed the gen 2 muffler on other cars appears to rust very easily. Even in California I'll see GR86's with rusty mufflers. I have a Verus diffuser that covers my muffler so maybe that has saved me from the rusting but I have never seen a rusted Gen 1 muffler so this has me concerned.
