D24t Muffler delete???

[myselfnjit]

I have an 86 740 TD wagon with 212k and the original muffler!!!

I have got to believe that this thing is just clogged full of soot so I am thinking of taking it off.

Anyone know what size pipe I will need and if it will be loud?
I did this for my TDI and dont even notice a difference except some cool turbo whistle, will this be similar?

thanks

Well original here in europe is 2 1/4", and i believe its everywhere.
About sounds, i cant tell yet, just doing whole new piping this week, upgrading to 3" with one smallest muffler i could find, and juust because law requires 1 here.

By the time its all the way out back, it wont be too bad. The sound is kinda like a cummins engine found in the dodge diesel trucks. Check out my videos for what it will sound like, I posted some up in the performance section. I had a larger section of pipe (2.5") going over the axle which made it deeper and louder. If you stick with the stock size it probably wont be too bad. You should throw the stock muffler away for sure though. If it turns out to be too loud for you, make sure to replace it with a diesel straight through muffler only. Regular mufflers from your local muffler shop will clog.

so I should get some 2 1/4" pipe a couple of clamps and a hanger.
Cool.

cut it off today, not really any sound difference.
One question though, what is the muffler looking thing further up the exhaust line, before the rear axel?

Just another muffler.
