At the inlet of Section 1, the factory piping is 2.25-in.
While it is the virtually the same on the Megan Racing unit, it opens up to 2.5-in as you go back through section 2.
Here’s a close up of the welds on the Megan Racing mid-pipe at the resonators (section 1). For some reason the factory Section 1 only has a resonator on one side, while Megan put one on each side—which is what we need to quiet things down.
Here’s a look at the other side of the Megan Racing performance mid-pipe. Constructed of T-304 stainless steel, it’s a real good-looking piece indeed, and it appears well priced.
The Megan Racing performance mid-pipe comes with new gaskets and hardware, which you’ll appreciate if you ever have to remove these again.
