Just curious if anyone could identify who made this downpipe? As I've learned more about my car and have taken things off I've found things that the seller was not 100% truthful about.

 

I want to say that is an old pettit downpipe.

 

I cant really help you with identification, but IMO if it fits properly and it does not leak than it does not matter who made it.

 

Getting the lower rear nut off was a major PITA! The stud almost touches the pipe when all the way tightened on so I had to slowly back out the nut and keep pressure on the pipe to make room for the nut to turn. Of course, this was my 1st time taking of the DP, so I don't know if all the others are like this or not.

Next weekend I'm taking off the twins, we'll see what fun that brings.

 

it looks fine. O2 sensor is in the wrong place to be an M2. its also not an HKS, and its not a mindtrain either

 

Sounds pretty standard with regards to removing the nut.

Looks like my Bonez DP from www.rx7.com

 

Found a shop just down the road from me what will ceramic coat it for $75. I think I'll wrap it heat wrap afterwards.
