• First off is anyone using this kit
  

• I have Pypes downpipe kit DOF10S, but which pipe is the drivers side and passengers side?

• Each pipe is labeled DOF10S-L and DOF10S-R, but does the L signify passenger or drivers side and does R signify passenger or drivers side?

• The L pipe is nearly 1 foot longer than the R pipe.

The left and right usually go by when your sitting in the car. so the right side would be passenger the left drivers.

I need some help.

I installed my Pypes downpipes, but the drivers side doesn't seal well to the manifold flange as the Pypes flange is for 2 1/4 with a tapered flange. The Pypes flange appears too big to seat well against the manifold flange and I cannot move the pipe and tighten it properly where the down pipe doesn't hang to the ground. Therefore there's a slight exhaust leak where the manifold and Pypes flange meet up. Does anyone make a gasket that I can use between the two flanges to help with the leak and with the adjustment to get down pipe more against the floor boards and not hanging down to the ground?



Thanks

I have a Pypes exhaust on my 72 Cutlass Supreme, but the previous owner installed it so I don't know specifically what kit it is. Its a 3" kit that hooks up to some headers. Let me know if me trying to crawl underneath and get some pictures would help you with anything.

I have that same setup on my 67 cutlass, the only way I could get it too work was to cut the pipe twist it then re weld. not saying it is the same just food for thought.

Once I adjust the pipe and then tighten the bolts the pipe points to the ground at 45 degrees. I assume I could remove it and have an exhaust shop bend the pipe upward. Not sure what to do about the leak at the flange though. Maybe the shop can compress the tapered flange to make it fit better?

Figured out that the pypes tapered pipe and the flange that bolts on are flush unlike a stock down pipe where the stock pipe tapered flange sits higher than the flange piece that bolts to the manifold. Second issue is that my factory manifold pipe outlet is 2 inches and not 2 1/4. So is there some kind of gasket I can insert between my manifold and between my tapered pipe area to get the stock manifold and pypes down pipe to seal properly?
