This has just arrived to my house.
Nameless 2.5inch 5inch Muffled Track pipe for the 2017+
After searching for a dedicated single exit. I have decided to go with this setup over a traditional cat back as the current offerings did not really suit my style. All single exhaust cat backs were a canister style with a large 5 inch tip. I wanted a simple OE style tip that wouldn't draw too much attention in terms of the looks department. With a bit of research, what i have found is that they all seem to be a bit either too raspy or not as smooth sounding for the 2017 year models. I also sometimes question "JDM" exhaust systems as most companies in japan now are out sourcing their production and with recent shortage in supplies along with sub par welds, it isn't as high quality as the US standard currently.
TLDR, i went with a quality US brand that is built here & made to order, so i know that i am getting the utmost quality...
First Impressions
for reference loudness scale
10 being catless headers straight muffler to
1 being stock.
Cold start is pretty loud for what it is. That's pretty expected with any exhaust for the ZC6/ZN6 Chassis, which i would rate roughly around a
7.
Once the car warms up after a few seconds the exhaust becomes pretty quiet maybe just a slight +1 volume over stock which i would rate around a
2-3.
Once you start getting the car through the gears driving around the neighborhood the drone is quite noticeable around 2-3k rpm range 1st-3rd gear... but easily manageable to my standards, id roughly rate the city driving to be around a
5.
Went it comes to highway speeds cruising at around 72-75mph on a 2017+ car. The drone is pretty much non existent and pretty quiet. I can easily listen to my music on a low volume and can even comfortable talk to my passenger without having to raise my voice. loudness wise id give it a
3
As for the sound, its very deep and tame sounding. Just what i wanted from this. There is no rasp whatsoever, and you can definitely hear that smooth equal length tone coming from the new header design on the 2017 model (which i do prefer over the zenki models, where the older model exhaust had more of a UEL sound to it in comparison).
Overall, i am very pleased with this setup and this will be more go to daily driving setup for now until i decide i want to switch things up. I do have eyes on the EVS Tuning 70-SSP catback but that will come at a later date....
I also have an exhaust hole cover for the passenger side and that will be installed ASAP :]
