Just recently took on a winter exhaust project for my Svart 401. I picked up a Duke 390 titanium header and cat delete, a 2018-19 resonator and I’m going to use the stock silencer until I can get a Yomishura R77 ordered. The final component is on its way, the Coober ECU and open air box cover. A helpful gentlemen at AMOC advised I keep the 18-19 resonator to keep back pressure and DBs in check. I’m really excited to get it set up and flashed…
The goals for the project are to improve ground clearance, sound and weight savings. I suspect we’ll get a power and response improvement, but it’s got plenty, so it didn’t make the list.
