Dinan Valved Exhaust Systems

Dinan valved exhaust systems are available in cat-back and rear axle back options for a variety of Toyota applications. These exhausts convey 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, Dinan exhaust systems are a straightforward install with precision fitment, just like you'd expect straight from the manufacturer. Mounting and proper fitment is where the similarities to the factory exhaust end, however. Fabricated from brushed 100 percent T304 stainless steel, TIG-welded and free of hydroformed pipe, each upgraded system is a marked improvement from its predecessor—both in terms of material/construction and overall looks. 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, 114.3mm (4.5 in.) exhaust tips emblazoned with the laser-engraved Dinan logo. The tip branding further cements any lingering doubt that the system visible is something above and beyond stock. 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 who want 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's the perfect blend of civility when not pushing the car or the full spectrum of auditory delight when in it. No matter the situation, Dinan valved exhaust systems are the answer for discerning enthusiasts looking for sound without sacrifice. Additional product features: * Maximum gains of +6 HP and +5 lbs.-ft. of torque * Enjoyably louder, sportier sound * Drone abatement technologies used to reduce cabin resonance * Dual 4.5 in. (114.3mm) double-walled clamp-on tips with laser-engraved Dinan logo * Larger diameter piping for increased flow (83mm throughout primary run vs. 80mm at largest point) * 100 percent 304 stainless steel construction * Retains factory valve control * Factory-like fitment with included mounting hardware * Tips available with polished or black ceramic coated finish

Dinan Power Control Units

Dinan Power Control Units deliver more power and more features with improved reliability and drivability than ever offered before, proving performance without sacrifice is alive and well! Dinan Power Control Units (PCUs) are in-line tuning modules based off over a decade of lessons learned in the category. At their core, the plug-and-play control units install between select sensors and the ECU, adjusting these signals to achieve increased performance that the stock programming is unable to approach. What sets them apart is their integration into more than just the fundamental boost sensors, but also additional connections--inclusive of OBDII, resulting in a more capable system that does more than just increase power. Dinan PCUs are controlled by a free Bluetooth app, available for both iOS and Android, and is home to all the potent features the device offers. Equipped with five different pre-set performance levels, you can use your smart phone and PCU app to change performance levels on the fly, revert to stock, set boost by gear, as well as monitor vehicle health via logging, customizable gauges, and code reading/clearing, ensuring a seamless tuning experience that even a novice can be comfortable with. Lastly, safety and reliability have been cornerstones of the Dinan brand for generations and not only does the Dinan PCU not hinder any factory safeguards or emissions controls but incorporates its own safety features as well. Going one step beyond our own internal protections, the PCUs also grant the end user the ability to monitor up to 20 different engine parameters in real time via customizable in-app gauges for verification of worry-free operation. Those same parameters can also be logged/viewed in app (or exported to CSV) for further scrutiny if desired. Dinan Power Control Units are available with a 2-year unlimited mileage product warranty or a 4-year/50k factory matching new car warranty. Select the Dinan PCU with the preferred warranty.
