Dinan Valved Exhausts for the Toyota GR Supra

Much louder lol l - it’s mainly the additional bass

After it warms up is normal mode similar to stock?

it’s pretty close. It’s a bit lower tone but maybe a few dbs louder

Yeah once it warms up it’s very mild in both modes while idling.

definitely considering this exhaust, how's the drone with OEM downpipe and valve open?

Some in car drone in sport mode, but nothing excessive by any means (2k-3k RPM and under load is the only time drone is noticeable - BUT normal mode stops it immediately).

Just did a 10 hour drive through the Asheville area/Copperhead Loop/blue ridge parkway yesterday with my wife and dog in the car. Exhaust is perfectly livable for cruising but can get really rowdy when you want it to.

OH and I got about 20-30 in car videos so far with Rayban Metas - mostly tunnels/sport mode fun.

I’ll try to post some within a few days.

Minimal at best. It's the only way I drive mine, in sport. I get no complaints from the wife about drone.

Awesome! I can't wait for my next trip up to Robinsonville so I can hear mine ripping through the mountains. Flat FL roads don't hit the same lol

Here are some of the better clips from the drive

Edited —— Stock downpipe

Yup all stock except the exhaust.

More than likely the smoke you are experiencing is just the muffler packing bags burning off. Romp on it for a half hour getting it very hot and they will totally burn away.

You must have been right, smoke issue has gone away. Phew, I was really stressing there for a little bit.

@Dinan_Engineering

Did you guys ever test the exhaust with a resonator?

We messed with the stock collector/resonator and our own muffler as an iteration (just a Dinan axle-back) but never created a version of the existing Dinan exhaust with our own resonated section that I am aware of. In the prior setup the the collector/resonator didn't address any problematic drone areas so we simply eliminated it to get a bit of extra volume.
