L15B aftermarket headers?
#4
The L15B does not have a 'header'. There is a single exhaust pipe section that has is two catalytic converters attached to the exhaust manifold. Then the 'B-pipe' or midsection, followed by the muffler. The 'header' is built into the engine itself. J's racing do have a section of pipe to replace the cats, 'B-Pipe' and the muffler though. I don't think you will be able to find any of them on their USA sites or that they are available to order (They wasn't last I checked but I haven't checked in months).
Aftermarket mufflers or a pulse chamber (Bisimoto) are available.

The cat delete, B-pipe and 50R all 'fit' without any issues. The cat delete will cause a CEL because the EGR tubing has been eliminated. On average, the car is faster however, the quickest time I have achieved was with replacing the muffler and a 2.5" mid-pipe (Not recommended due to sound).
Just replace the muffler with a straight through one (whether quieter or not) and you will be good with the exhaust. The stock muffler is not straight through (You'd see what I mean if it was off of your car). Just my opinion!
