Anyone make a cat bypass for NA cars? (specifically my 86). I trashed the O2 sensor attempting to remove it, so while I'm in there....

Of course, this is for a track prepp'd car for those enviornazis'. harump.

have a muffler guy cut the cat off and weld a 2.5" piece of mild steel in between and you have a cat-bypass.

Not in Penna. my friend.

Muffler shops around these parts are all afraid of the $10,000 fine for Cat tampering. Easier to do a complete bypass and keep the orig pipe for inspection purposes.

You can go with the Bursch header/cat bypass. It's also lighter than the stock exhaust due to thin tubing. However, you have to realize it only costs 250 or so, so its not the highest quality product and will resonate due to the thin steel tubing.

Lots of places, Pelican parts, Performance parts. I think GPR does too.

I assume you've done your homework and know what will happen to your power band?

That's why you put a nice kink in the pipe to increase backpressure.
