*NOTE This does not fit the 2019 STI or the Type RA Exhaust. - While this exhaust connects to the factory downpipe and fits the factory bumper, the routing and flange locations are not the same as the OEM exhaust system.
The OEM+ 'STi Performance' exhaust system has a very odd sound signature. While it has very little sound at idle and low RPM, once it achieves cruise RPM's it tends to have a pervasive drone, which intensifies as throttle is applied, and then goes away entirely leaving very little sound of the exhaust above 5000rpm at wide open throttle. Seemingly the inverse of what most people want out of a performance exhaust, nameless took it upon themselves to design a muffler delete and do extensive testing of that design. Lo and behold, we end up with an exhaust that has no drone at cruise, a nice sound at idle and tip-in with a more aggressive sound above 4500RPM at heavy throttle. And all able to be directly bolted up to the STi Performance / SPT midpipe at a reasonable price point.
Details:
- CNC Mandrel Bent Tubing
- 3 bolt SPT Specific Flanges
- manufactured in Woodland, Washington, USA
- All of the tubing features a #4 brushed finish, with the exception of the 3.5" mirror polished tips with a neochrome finish.
- 100% T304 Stainless Steel Construction
- Precision Fabricated and Fitted
- TIG welded by hand
- T304 Exhaust Hangers, ensuring that your exhaust fits out of the box and stays where you left it.
Benefits:
A simple modification like the replacement of the back muffler box on a car can transform the day to day driving experience for the owner of the vehicle, and this exhaust is no different. We love to claim that the first and foremost benefit to our exhaust systems are that they sound incredible and really make driving more enjoyable. Baffled/chambered mufflers are an amazing invention of science, with the ability to cancel specific frequencies of sound to provide a near silent operation. For those of us who are enthusiasts, however, mufflers and resonators that are designed like the factory ones are provide us with zero feedback. Switching to a muffler delete promotes more tone across the powerband while eliminating the engineered drone associated with the STi Performance / SPT exhaust in the midrange.
Beyond the sound signature and improvement in powerband, the most noticeable difference in the addition of our exhaust is the weight savings of 23.3 pounds!. The replacement of a baffled rear muffler with a straight section of tubing or straight through muffler design generally nets 8-12ft lb on the STi and 6-8ft lb on the WRX.
Nameless exhausts are welded by hand, by a human operator who has control over all of the variables of the welding process to achieve a superior weld form. In stark contrast to this process, much of our competition uses an auto-TIG solution which automates the rod feeding and heat control and uses an unskilled laborer to simply rotate the seam of the part through the auto-tig system. The result is a weld form that is oversized, which results in an exponential increase in voids in the weld form in any instance where the overlap between these oversized weld convolutions does not fully cover the void in the previous pulse of the weld. While many of these auto-TIG welded exhausts look like they are similar in construction, they're anything but.
