Infiniti Q50 / Q60 Lower Down Pipes and Cat-back Exhaust
Q50 / Q60 Cat-back Exhaust With the release of the new VR30DDT engine platform which is equipped with a twin turbo setup, we noticed that the size of the exhaust piping from the factory was not adequate enough to be able to provide power efficiently – even at factory boost levels. Increasing the overall diameter of the piping by half an inch and incorporating ultra quiet resonators along with v-band clamps and 4.5” polished tips allowed us to build an exhaust that produces an increase in power and still retains the elegant look of the vehicle.
We have designed this exhaust to be an OEM direct replacement that will not require any additional cutting or welding to install, giving the average enthusiast the ability to install it themselves. A 2018 Infiniti Q60 Redsport was used during the research and development of this exhaust system and the dyno comparison was performed on the same day. The tone of the exhaust increased slightly when compared to the stock exhaust and created very minimal drone in the cabin despite the larger diameter piping.
The results are the following:
Peak Horsepower: 19 rwhp @ 3700 rpm Peak Torque: 28 ft-lbs of torque @ 3700 rpm Additional benefits to the exhaust were the following: – Boost stayed consistent throughout the powerband – More Aggressive tone Lower Down Pipes Introducing our SOHO Motorsports Infiniti Q50/ Q60 Lower downpipes for the VR30DDTT, made out of T304 stainless steel and 2.5″ diameter piping. We have released an updated version of our VR30DDTT lower downpipes, based on feedback and requests from potential customers.
These remain to be made out of 2.5″ diameter T304 stainless steel piping, but the big change is our pipes are now mandrel tube bent providing a much cleaner look for the downpipe itself. If you have our previous fear not, these are covered by our lifetime weld warranty and should not be a noticeable difference in performance. During testing with our lower downpipes, we saw an increase in horsepower and torque throughout the powerband, relieving back pressure in the engine when increasing boost. However please note, we have not tested this independent of a catback exhaust. We are basing this data, from adding the down pipes to our already existing catback exhaust.
New gaskets and bolts are included!
