About to get my tax return and I really want to get the 4-2-1 headers for my 2k1 tib. The only thing holding me back is the thought of having to do my entire exhaust system. I don't think I'm going to have enough to do my full exhaust right now, but is it going to fit right? Do I have to, should I wait till I have enough to do the complete exhaust?

Any help would be appreciated, thanks guys!

 

Doind your whole exhaust with the headers would be a plus but you don't have to the headers will improve your performance even without the whole exhaust upgrade but I would suggest getting it done sometime down the road. As far as it fitting it will you just might have to drill a hole in the headers if you have 2 sensors in your manifold that's all so I would go for it.

 

I assume I have the second sensor and will have to drill, thats not a problem, I don't think they'll charge much for that. i also want to keep it fairly quiet (hehe, not too quiet!) and reading through previous posts unless I get like 2 or 3 glasspacks, sticking with stock exhaust would be sufficient. Cool! I think this is what I'm going to do. It was really a toss up between lowering and headers, but I'm really more interested in speed, since the tib already has a real nice look.

 

GETTING HEADERS WITH THE STOCK EXHAUST WILL HURT NOT IMPROVE PERFORMANCE, ( yes I found the caps key ). Get the headders and save up to do the whole exhaust, install them all at the same time, you'll have to cut and relocate/replace the cat if you get a cat back system before headers. Trust me it's best to do it all at once and to keep it quiet a large 22" or larger glass pack will do. The 2nd o2 sensor goes behind the replaced/relocated cat into a hole made for it in the exhaust, you'll have to extend the wires 1ft but any competent muffler shop can do it all easy for you.

 

Why must you crush my dreams!

 

Humm Did I do that rolleyes.gif

 

What if I just get a new muffler?

 

Also, I added the header with the stock muffler (I had the mid pipe already) and it made my stock muffler rattle really bad.
I finally got a new muffler Tuesday.

 

You should do a cat back with a high flow cat, and get the headers later...you want to go small to big, not big to small.
