kunas Posted October 22, 2008 Report Share Posted October 22, 2008 where should I go to buy some that are reasonable. all I have found are around $400 for the both and the y pipe. should I try to find a performance set or stock replacement? should I try to buy a universal and get it welded in? I'm strapped for cash, my boy is being born any day in the next few weeks, and my wife is not working. any ideas? Quote Link to comment Share on other sites More sharing options...
eddieo818 Posted October 22, 2008 Report Share Posted October 22, 2008 Maybe check your local Muffler shop for a used one?? Quote Link to comment Share on other sites More sharing options...
supersub Posted October 22, 2008 Report Share Posted October 22, 2008 option 1 replace with factory set up------bookoo dollars option two remove said y-pipe and remove what's causing the clog-------labor only,clear rear 02 sensors. option three remove bad cats and replace with china knock of version from ebay-------@ 39.0 ea plus welding exspenses option four replace with dynatech or stainless works set-up------worth every penny but costly good luck Quote Link to comment Share on other sites More sharing options...
kunas Posted October 22, 2008 Author Report Share Posted October 22, 2008 thanks for the info. I don't think simply removing the clog is an option. this thing is rattling like aluminum cans I checked the dynatech... way out of my price range for the next 5 years. but great idea, thanks Quote Link to comment Share on other sites More sharing options...

dcairns Posted October 22, 2008 Report Share Posted October 22, 2008 Post around on the forums. You may be able to find somebody who is ditching their cats who will sell them to you fairly cheap. Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted October 22, 2008 Report Share Posted October 22, 2008 I would check with a local exhaust shop to see if they can get you used cats or some cheap aftermarket replacements....... Quote Link to comment Share on other sites More sharing options...
kunas Posted October 24, 2008 Author Report Share Posted October 24, 2008 NO GO, on the exhaust shop. two different places said they couldn't get uni's into that location. no one around here sells used cats. I just ordered the whole y pipe with both cats for $320. shipped it's the Eastern company's setup. advertised to be high flow. I doubt it much mor ethan stock. we'll see if I get any gains. thanks again guys Quote Link to comment Share on other sites More sharing options...
