Whoa $180 I have not priced one yet but thats huge.
The flex pipe opening is a rough 3", kind of oval almost.
I'm feeling better so I'll go for the install this weekend, I have a buddies shop to work out of and he'* got a hoist

$180 is a REDICULOUS price for an 02 Sensor. That should be illegal! And the flex pipe is definately 3".

Hoists are awesome. At the career center I go to, we have hoists we can use, and every friday we can bring in our own cars and work on them, so I bring in my car to do a bunch of stuff to it on the hoists, but they won't let me touch my exhaust for some reason. They said something about it needing to have a cat or something.

It'* about time I got a response from you Shawn, you must have been very busy.
Damn auto cops. They are probably worried about losing their license from the EPA
You're lucky to have the use of a hoist regardless.
Don't forget that'* a Canadian price for the O2 sensor, so it would be equivalent to about $120 US.....still too much IMO.

I'll let the muffler shop worry about matching the 3" connection to my 2 1/2" exhaust. It will be some time later until I consider replacing the rest of the exhaust. It is still in mint condition.

My firebird still has it'* original stainless mufflers and tail pipes.....I would have a hard time getting used to a different sound and it sounds so good the way it is.

I was wanting to go with dynomax mufflers to open it up some more but my exhaust is still like new so I may wait too. I'll flip a coin on Saturday

:? If you get the high flow cat downpipe or the off road downpipe to connect to the headers, do you still need to have anything fabricated to connect it to the rest of the stock exhaust :?:

Pdad...dual Magnaflow....you gotta do it

Flowmaster baby!

Update - progressing slowly but steadily. Down pipe is removed. Next is the rear manifold. So far everything was removed from beneath.
Going to have to figure out a way to hold up the exhaust system when I drive it open headers to the shop for the welded connection. :?
Headers haven't arrived yet. Maybe next week.

Mine took like 25 days to get here, held up in customs had to pay $54 at the post office.

Guess I'm being optomistic.
It'* only been two weeks, so maybe it'll take another two...??....but I'm hoping yours took longer because you ordered over the holiday period and lost a good week there.

Yes, I expect the government to get their cut in taxes when does arrive. When all is paid and done, I estimate the headers will cost me approx. $1500. Certainly not a cheap mod for 20 hp...........$75 / hp.
The 1.9 rockers have a better return on investment but hey, I don't justify my improvements on $$ alone. The ceramic coating will also have some benefits in keeping the engine bay cooler and I expect a more pleasing exhaust sound.
It'* hard to put a price on satisfaction and pride of ownership.
