Yes it is a "muffler" if you will between exhaust manifold and turbo. I researched several months ago and recall ended I'm pretty sure several years ago. Worth a try though. I will check into the monster guy. I have found acouple of worthy early 126's to get manifolds and related parts to switch over. Pipe seems alittle easier. I disconnected egr and bypass. Car really scoots now. Maybe gained 1gal/mi, about 28mpg now. Smokes considerabley more at WTO. Dont want to clog up trap. Thanks for the Suggestions
