where do i get headers for my 3.1? i cant find them anywhere, and if i put headers on, what would it sound like? deeper? its pretty deep as it is. i have 2 1/4 straight exhaust to the muffler in my sig, no cat. can i cut the y-pipe right before they join as 1 even tho i have a o2 sensor? i thought if i cut the pipe the o2 sensor would only read exhaust from 3 cylinders instead of all 6, and it would read incorrectly and id have a check engine light again, is this true? thanks

I don't know the answer to your question but I am wondering why you want headers for the V6? They are a fairly costly item and will not have much effect on the power of your engine.

When I was young, I used to dream about hopping up my V6 Firebird because it was what I drove. But lack of money kept me from doing so and in retrospect I'm glad that was the case. Bottom line is that it would still be a fairly puny engine with low return for my dollar. About 5 years later I bought a '68 El Camino with a 350 V8 and starting playing. Stronger platform and better bang for the buck (for drag racing anyway).

Uhhh.... the O2 sensor on TPI engines reads only from the drivers side bank.

Anyway... the problem with your theory is that no one makes headers for your car. Nobody. The closest I could find (yes, I did look) is a set for a pre-90 2.8: http://www.hawksthirdgenparts.com/inc/sdetail/39659

As for the sound, that depends on the rest of your exhaust, and your engine. If you really want decent sound out of that beat V6, I'd say drop the fart can and get a decent straight-thru muffler. Mount it closer to the engine, and then use a 45* turndown tip.

Ahh, yeah the 3.1's were a more modern style. Still, you can just weld the bung in wherever you want it.

[Danked]

this is my y-pipe, if i cut it at 1, would the o2 sensor still read correctly even though it wont be reading the exhaust from 6 cylinders, it will from only 3, will this cause it to read incorrectly, is what im trying to say? i found some 3.1 headers on ebay a few weeks ago but dont see them anymore

[Dewey316]

I really wouln't waste the time or money for a 3.1. If you want to build a performance car, then use a V8 car, the money you will toss into a 3.1 is a waste. At the end of the day, you could spend thousands on your V6, and still only get to the stock levels of a V8.

[aaron_sK]

Why not just weld the O2 bung into the new Y-pipe?

*Edit:

[Danked]

haha, id love a v8. but i dont have one, so this has to suffice, we're gonna swap out my v6 and put in a 350 from my dads pickup, its got edelbrock intake and 202 heads. just alot of work, + i need a tranny for it and i want power for my application right now, its gonna take months to do this and i just want power like right now. would the 350 sound nice if i had dual 3 inch with headers all the way to the back with 2 of my mufflers?

[aaron_sK]

True duals in a third gen is a pain. It's been done:

.... but it takes a lot of work and cash.

If you want cheap badass sound, pick up a Dynomax bullet or something like that, and run 3" single from your Y-pipe out the back. You can mount the muffler along the driveshaft and retain your dual tips, or just mount it paralel to the rear bumper and run a single outlet.

If you're going with the V8 swap idea, I personally would start in on the frame and suspension. Lower it, install subframe connectors, and go with wide tires all around. You're going to need to get all that V8 torque to the ground once you do the swap.

[Danked]

ok ill just keep the crappy ass 3.1l that wanarunhard is going to be installing pretty soon and just do frame / suspension work. im planning on buying 19 inch rims for the front and back, 315s on the back and either 205s or 225s on the front. id rather raise it than lower it, maybe next thing ill buy is air shocks

~edit~ HOLY GOD THAT EXHAUST LOOKS BAD ASS

[aaron_sK]

There are two reasons to raise a car:

1) In the rear only to fit larger tires for better traction, instead of tubbing.
2) For ground clearence in cars to be driven offroad.

I doubt you fit either one of those, so why raise it? If you want the whole rediculous 60's jacked rear end look, why not just buy taller tires? Lifting your rear suspension will just look dorky.

[Dewey316]

It will look stupid if you raise the car up, and put 19" wheels on it. The large wheel and small sidewalls make any fender gap look bigger, if you raise it up too, it will look really bad, that is just my humble opinion.

Maybe, instead of having all of these threads about this and that and so forth, maybe should start at the BASICS.

What is the goal for your car?
Do you have specific 1/4 mile time you want?
Do you want it to handle well?
Budget?

so on and so forth. Really dude, you are basicly asking all sorts of question, with no real direction. Most of us on here have spent a lot of time working on, and building these cars. If you tell us what it is you actualy want from the car, then maybe would could actualy point you in a direction to get you to that goal.

i want it to look all beefy and when i got new tires it will, hope they dont off my speedometer too much

[Danked]

1. i want low 12's with my v6, i want it to sound good, look good, burn out until i stop, look all big and beefy in the back.

2. i want low 12's with a 350, and same, i dont care how it handles, id like to be able to take corners pretty easily but not like a rice burner, (ie 70 degree turns at 60) i want ppl to say "wow" when i drive by and they stare

I have a 383 stroker in my Z28. I have taken it to the track 4 times this year and havn't hit 12's yet. The best i have ran is a 13.3. I hook up good off the line, but the only thing killing me is gears. I have either 3.08 of 3.23 and those are making me lose time. You need to have the right gears to go fast.

Like Dewey said it takes money to go fast, I have put over $4,000 in the engine alone and i'm still not happy with the performance of my car.

I also have true dual exhaust that dumps out the side, and i wouldn't recomend it if your car is you daily driver. My exhaust is maybe 2" from the ground and anytime i go over a bump, it scrapes the ground. [/quote]

[Danked]

we're going to rebuild it after we pull it from the truck, 11:1 compression, edelbrock non-egr intake, 950 cfm holley carb, high performance cam, lifters rockers bore the heads, everything. period. right now the 350 is prolly pushing like 125 hp, my camaro could easily waste it, so when i get that done ill get back to u guys and we'll work from there, btw are blackout taillights illegal?

[82camaro383]

Isn't a 950cfm carb too much for a 350? My 383 has a 750cfm edelbrock and i had to jet it down because it was dumping too much gas.
