I'm starting to think: Cut the stock mufflers open, wrap the perforated tubes with header wrap, keep the packing material, and weld it shut.
As for the H pipe: The Akrapovic 335i exhaust has an X pipe, which they claim is better than an H pipe. It seems that the H pipe is worth keeping.
So, can anyone recommend a good (and open minded) muffler shop in the Burbank/Glendale CA area?
