A number of years ago I bought a straight through muffler in the USA in Cleveland for US$ 14.99



Least expensive at Amazon.ca

I bought a totalflow from amazon for $40, honestly the best $40 muffler I've ever bought. the fit and finish was perfect, the steel was thick enough. Easy to weld. Lots of models to choose from to ensure it fit. Was exactly as described, dimensions were bang on. They have very clear pictures showing the guts so you can choose a model that fits your needs.

On my truck I went with a glasspack style but on the car I chose to use a more conventional muffler style but went very free flowing.

I wouldnt hesitate to purchase one again

No reason, since the DPF has plenty of muffling anyway. Unless you really want to save 30 pounds aft of the rear axle.

Muffler doesn't do a lot on TDIs. most of the muffling happens at the turbo, the rest at the DPF and cat. You could straight pipe the car and it wouldn't be a lot louder.
