Hi. Im looking to add a straight throught pipe to my 2.0tdi jetta. I want to get that nice "pooow" sound wen changing hear but dont want the exhaust to be too loud. Which muffler should i straight pipe, or is there another alternative. Any ideas on this?
Performing a muffler-ectomy on a MKV TDI really doesn't change much.
I own a 2010 TDI w/ DSG and have a Banks Power exhaust system on it (which is essentially no muffler and just piping from the cat. The CR engine has 3 (or maybe 2, don't remember) cats and a DPF and those items alone cut down almost all of the volume. Ask anyone who has removed the muffler on a MKV TDI and they'll all tell you the difference is so minimal it's almost none.
for reference, under load, I hear a slight depth to my exhaust now. However, the key word is slight.
Removing a muffler vs straight piping should be a huge difference. Coming from a petrol engine, anyway. I really shouldn't be chiming in about TDI, since the only diesel I've owned was my tow truck.

someone said it best, straight piping the exhaust won't give you that desired effect. You'll need a down pipe and some cat deletes. don't worry, no emissions on diesel. Start with the down pipe and muffler/resonator delete. Seldom do you find people who enjoy strait piped anything unless they're race cars. my friends straight piped E28 335 is one of the most ferocious sounding cars I've ever heard and if it weren't for the fact that he shot fireballs I would hate it. Honestly, he comes down my block and sets off damn near ever alarm....and that's him babying it!
