Title: standard exhaust size?
Post by: Vohaul on December 10, 2011, 04:06:03 pm: My stock exhaust has rusted out on the first muffler (least i think thats what it is)..(the smaller muffler in front of the rear axle)...Seeing as its close to xmas and im already poor:) ...i am just thinking of getting a replacement piece of bendable pipe..and some u bolt clamps to effect a repair until i can take it in for a whole new exhaust. after xmas...

My plan is to cut out the first muffler and replace it with the bendy pipe (you know the pieces with the steel braided like section in the middle you can get from can tire....)...

Can someone tell me what size / diameter the stock pipe is on a 94' AAZ 1.9 turbodiesel jetta....

Thanks

Paul
