My rear muffler is rusting through and I'll need a new muffler for my 91 jetta eco diesel, I can get a non turbo muffler for $42, the turbo version seems to be anywhere from $100-$200 depending on where you get it. Was wondering if any of you guys have used a non tubo muffler on a turbo, will it fit and perform right?? What adjustments will be needed for proper fitment if it will work? Please post or you can call me at 434 996 7643. thanks
