Description:

Evoke passion and excitement with the Dinan Valved exhausts for the GR Supra! Conveying the sweet sounds of a deep, rich, euphonious note that are unmistakably Dinan in addition to retaining the flexibility of valves, Dinan exhausts are the epitome of sound without sacrifice.

Utilizing factory cut points and mounting mechanics, the Dinan exhaust system is a straightforward install with precision fitment just like you would expect straight from the manufacturer. Mounting and proper fitment is where the similarities to the factory exhaust end, however. Fabricated from brushed 100% T304 stainless steel, TIG welded and free of hydroformed pipe, the upgraded system is a marked improvement from its predecessor - both in terms of material/construction as well as in overall looks. In the case of the GR Supra 3.0, for weight savings and simplicity, the stock single to dual pipe setup has been abandoned in favor of an enlarged, free flowing single pipe system. This pathway feeds into a muffler that limits frequencies associated with drone, as well as assists in altering the overall tone of the setup to deliver the signature low Dinan rumble. The no-nonsense design allows shocking versatility in sound levels when paired with features, like valves, often associated with more fanciful alternatives. The unabashedly spartan, yet effective, pipe layout forces gasses to escape from the rear out of massive dual, straight cut, 114.3 mm (4.5-inch) exhaust tips emblazoned with the laser engraved Dinan logo. The tip branding further cementing any lingering doubt that the system visible is something above and beyond stock-- if it was not already apparent by the blissful music permeating from them.

Unquestionable enhancements to the overall chorus emitted through the Dinan system transcend all modes making the vehicle a delight to drive and enjoy. However, for those that wish to have options to limit the extraordinary soundtrack for late night or early morning arrivals/departures (or any number of other reasons) factory valve control is retained. This effectively makes the system behave similarly to a straight-pipe system that promotes maximum flow and volume when the valve is open and emit more subdued resonant vocals when the valve is closed, and exhaust gases are wholly redirected through the muffler. It is the perfect blend of civility when not pushing the car or the full spectrum of auditory delight when in it. No matter the situation, the Dinan valved exhaust system is the answer for the discerning enthusiast looking for sound without sacrifice.

So this exhaust is 3.25" at it's smallest point?

On the primary passenger side pipe, yes. The pipe offshoot going into the can is 2.5" and the pipe exiting the can on the drivers side is 3" but finished at 3.25"

Nice!

Does this fit Euro cars with OPF?

 

[stormgreysupra]

This is the design I was looking for, just wish the piping diameter was 3.5 inches. It would have been the perfect exhaust.

 

[Sharocks]

Uhh can we get slash cut tips?

Straight cut tip with the stock diffuser looks kinda weird IMHO.

 

[Isaleus]

hmm I wonder how bad drone is without a resonator. But looks great and sounds good too.

Never been fit with any Euro/OPF cars but would likely require some minor adaption at the mate point.

Our typical process is upgrade the pipe size to "the next one up" for numerous reasons in both sound and fitment. From 80mm that meant 3.25" was chose. I think it worked out well and sounds pretty good. =)

Straight cut tips have been a Dinan staple for decades. No plans on changing that as the default Dinan tip. Perhaps in the future we will offer supplemental add-on offerings but there is nothing to expect in the near term. The alternative for anyone who doesn't like the straight cut tips is to source generic slash cut tips 3.25" from any number of outlets. Just needs to have a 3.25" inlet/pipe size and an overall length of roughly 5".

No drone to my ears but everyones' sensitivity to drone (and what even is interpreted as drone) varies.

Looks very interesting
Seems like the cut is made just in front of the factory resonator?

Depends on the system. The 4 cylinder kit is essentially an axle-back with the cut point just behind the resonator/collector. The 6-cylinder kit however is an cat-back and replaces the entire system post cat. Product pages both link the PDF installation instructions if you wanted to get a bit more in depth of what is required for either system.

Nice instructions!

I appreciate that this is so well priced! I've been really sick of the "Supra Tax" making me choose between getting stuff from unknown companies/sketchy people or selling my kidneys for parts cash.

Ordered Monday, got here Wednesday, put it in Thursday (today). I am very happy with it already, the 2 people still at work when I put it in liked it a lot, and on the drive home I already got compliments! Also I am ready to apply for my Dinan badge lol

 

[RyanA90]

Looks and sounds sooooo good!

 

[STi_to_GRzupra]

Excited to see this new exhaust.
