Ok i had thrush turbo mufflers on my car after my headman longtubes a s bend pipe to clear from but one of the got torn off by some railroad tracks so i put my old set of dynomax bullet mufflers. I can feel a good size loss of power and torque all around even on the top end so i read in hotrod that with longer collectors i could problay gain my lost power back but my question is do i have to put it before or after the muffler does it make a difference?? i rather but it after easier to hang mufflers.
