TRD Exhaust Pipe Diameter - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Jacob G. · 01-09-2013, 10:19 AM

Hello,
I was recently trying to locate the pipe diameter of the TRD exhaust for the scion fr-s and have been unable to find it anywhere... Anyone know the dimensions?

I'm the same way I already own it and I still don't know, just trying to plan for if I need to switch exhaust systems when I supercharge

Bump... Does anyone know?

cruzinbill · 01-11-2013, 09:42 AM

its more than likely 2.5, Im surprised no one that has it has measured it.....

wparsons · 01-11-2013, 10:53 AM

I think it's 60mm?

Jacob G. · 01-12-2013, 11:04 AM

Bump... One last time to see if we can get a definite answer

Dont have an answer but looks to be 4.75 compared to my 4.5 inch.

Thats what she said.

Im also sure its close to the 2.5-2.75" piping up to the tips. Im sure the tips are about 3-4" each. Idk because i don't have the exhaust, but its not too hard to measure... Few tools and a measuring tape.

I went out and measured my TRD exhaust today (O.D.)... So the axel back portion is 2.5" (8in circumference) but the mid pipe seemed to be smaller. I measure the diameter with measuring tape so not extremely accurate but when I held it up it appeared to be 2.5" but the circumference is only ~7in so hard to understand that math. I have read that changing the mid pipe doesn't translate to gains at least stock but I'm sure with forced induction you may want larger diameter.

Is this just an axle back exhaust like the Greddy?

Use a piece of dental floss, or fabric, or fishing line etc and put it up to a tape measure if you dont have a flexible measuring tape like one used for tailoring etc. Could be 2.25 and 2.5 axleback- and yea if planning to boost you'd want at least 2.5 imo especially on a frontpipe+midpipe.
