Pre cat pipe replacement
Anyone ever have to replace their precats/pipes?
If so, what did you use to replace them with and how bad a job was it. I have exhaust leak from a crack or hole so thinking about going from the manifolds on back and have it all be good at the same time so just looking for advice and hints. Scott/Omaha

Re: Pre cat pipe replacement
I just did the same. I had a shop create some pipes to weld in the 2 Magnaflow 50004 cats I provided them. Cost: about CAD$400

Re: Pre cat pipe replacement
Did the shop say how bad a time they had with the manifold to pipe bolts getting them off?
Also, did you do anything else with the exhaust from the main cat on back? I assume they also created bungs for O2 sensors? Last edited by scottsubarus; 04-16-2009 at 02:55 PM.

Re: Pre cat pipe replacement
Can shops even legally replace the precats with a pipe? I know shops cant legally create a straight pipe to replace the regular cat, but I dont know about the precats. If they can't "replace" the precat, I guess you can just have them create a pipe for "race days" that you can put on yourself.

Re: Pre cat pipe replacement
Stebro in Toronto makes a complete system. You can buy any pieces you want.
I picked up front pipes, manifolds, cats from a salvage yard in the US prairies. No rust or holes. Stebro pipe from the cat to muffler.
