not really maybe lengthening the wires on the o2 sensors. the nuts on the exhaust manifold studs are gunna be a bitch to get off. Use a lot of penetrating oil to get them off, if you have an impact wrench that will make it a lot easier. that bracket coming off the block to the exhaust and to the intake manifold can be a bitch aswell. other than that its a fun process.

My header came with the O2 wire extention harness. Besides most have O2 bungs located on the collector of the header, and/or on one of the primary tubes itself, atleast for 92-95s.

What kind of Header are you going with??

There's 2 ways of doing this.

1. Remove your y7 Exhaust Manifold and Install your aftermarket Header. Go to a Muffler Shop and have them put a Catalytic Converter with whatever Size Exhaust you're going with. While they're at it, tell them to put a bung after your Cat. so you can put your secondary o2 Sensor.

2. Buy Everything Aftermarket for a Ex and put it on yourself.
Header, Cat. and Exhaust. And then tap after the Cat. for your secondary o2 sensor.


Which ever way your go, you just need to extend the Wires for the Secondary o2.



Now do work and Post Pics :bigok:

Here's what I did...bolt up new header...extend my wiring to go into the secondary bung on the header.

Drove open header to my shop (took careful planning to make an appointment)

had 2.25 piping done through a magnaflow res.
