how much do you think it would cost to:
-weld O2 sensor bung into collector
-make custom 3" y pipe to hooker catback
-install and weld hooker catback in place
-make custom hangars to hang 83 and on exhaust on an 82

Any opinions?
Also, do you think that it would be better just to grap some hangars off some wrecked thirdgen and put them on?
Thanks

 

I had the O2 bund welded in for $10.

 

so...what am i looking at here then, maybe $200, $300, or $400 dollars in work.

 

I wouldn't know what they would charge you for what you are needing done. It all depends on the shop you take it to.
If I had to guess, I would say no more than $200.

When I put the SLP Headers and Y-pipe on my car, the Shop I went to welded in my Sub-Frames, Modified the Y-pipe because of the SFC's, Ran Duals with a Custom built X-pipe, Header flanges added right before the rearend. This took him a day and a half to complete. $800 from my pocket.

Yours will not be as involved as this was, I couldn't see paying more than $200 for it.
