hey...........ive been wanted to mod my 97 3.0 for awhile and plannin on gettin som dc sport headers and magnaflow muffler. umm i no it wont get me that much of a gain but i dont really wana swap. BUT i was reading how you acctually loose power from getting headers?????? or is that only on the four bangers? also wuld i get the most gain from 2.5 piping instead of 2.25

 

more air/fuel= more power 2.5 ftw.headers,you'll never lose power from headers unless there not secure.cocoa's with ex/in/head/pull/tuned gave him 12whp.....

 

dam thas pretty good.............hopfully i get half that lol

 

The actual intake, headers, pullies and exhaust gave me 13whp. The tuning itself gave me and additional 12whp. So a total of 25whp.

 

what do you ask for when you "tune"? i heard it talked about but i don't know what is involved...what do i need to ask for when i go to a tuning shop?

 

my bad,and not bad.damn,tuning gave that much an increase?did you have a control?

 

Don't get DC headers unless you wanna pay to have the downpipe bent. Go with SSAutoChrome, no bending required. And you will gain if your car can breathe better

 

On the 3.0 go with the 2.5" piping. The 4 bangers get 2.25".

And yeah, look out for those DCs, I read that they burn up.

 

2.5" piping all the way

 

I think you should get 2.25 for the 3.0. If you get 2.5 you'll lose back pressure which means you'll lose hp at the low rpms with 2.25 it won't be as bad. When I went 2.25 I noticed a loss of hp on the low end and it's gotta be worse with 2.5. For the record I know that stock is 2.25 but the axle back is 1.75 and what I'm saying is that when the 1.75 got converted to 2.25 I lost back pressure and lost hp at low rpms. I wouldn't get 2.5 unless I was putting a S/c or turbo on.

 

You might lose some back-press when going with 2.5 (but everyone else seems to be ok with this on their car so...). But, if you run the 2.5 pipes with resonator/silencer and non-rice muffler (conservative muffler like magnaflow, etc), the res and muffler will compensate for the small loss of BP... in the end, you will lose a bit, but your car will breath better = you'll be happier

 

I also have the magnaflow 14816 muffler and the magnaflow 22 resonator and my car definitely felt slower off the line with that nad 2.25 piping. I just think 2.5 is too much unless you're doing some sort of forced induction.

 

Some people do plan to do that, i should put it in my mods list and be like suprachica

 

that's ussually for higher powered cars, they mess with air/fuel mixture and other stuff

 

If you change the stock setup of any engine, you will need to tune it to get the best performance out of upgrades. I plan to have mine tuned after I get more performance upgrades installed.

 

yea i would go with a DC Sports 4-2-1 Ceramic Header, some sort of 2.25 straight pipe into a exhaust system of your choice. cant go wrong.







o shit i must be blind, i thought it said 2.2/3's only. my bad

 

yeah thats true also, but most of the time the high powered cars get tuned because it runs like crap/ very rich if it's not tuned.

 

actually i put one of those test pipes (cat eliminator) on my car and i lost gobbs of low end power. the top end was better but not enough of a gain to make up for the bottom end i lost. so by getting bigger pipes you are losing back presure, which only really negativley affects the bottom end.

i would get headers and a nice cat back system, and be done with it. headers is by far the best bang for the buck on the 3.0's. theres a dyno on that shows almost a 30hp gain. to the crank.

 

wut wuld u recommend for a nice cat back system...........link maybe

 

So Wilp, wat you're saying is that a 2.5" piping on a 3.0 is actually counter productive? Also, can you clarify the differences between axleback and catback? I always think that catback refer to the part from the Catalytic converter back to the muffler...

Here's what i have in mind for my set up: Hi-flow catalytic converter, custom 2.5" piping, 22" resonator, Magnaflow muffler... Can anyeone chime in?

 

you can custom make your own. but anything like greddy, dc sports, tanabe, or apexi is fine. you cant find those for under 450 if you really try.

 

axle back starts at the rear of the back wheel and goes back to include the muffler. the cat back goes from the cat to include the muffler. one is about 8 feet of piping and the other is about 2.5 feet.

 

and i would say eather 2.5" pipe or hi flow cat. i had a hi flo cat on stock piping and a magnaflow muffler and i lost the back pressure needed to have a decent bottom end. the resonator shouldnt make much of a performance gain but help with the sound alot. if you have to do one or the other i would go with the 2.5" piping. other than that i would stick with the stock piping.
