I have a 2004 chevrolet cavalier ls sport with the following upgrades to it:
- rsm intake w/62 mm throttle body
-rsm lightweight crank pulley
-pacesetter catback exhaust system
I have seen a good difference with just these mods...i dont want to go turbo or nitrous on it. wondering what the next option would be...would a pacesetter header be a next step or not...a loud exhaust is not something i want...it is loud enough with my current setup!
The ECOTEC is a great engine!
if you want low end and you want to add a header go with a 4-2-1
Noooooo you bought the Pacesetter exhaust system! I hope it works better for you than it has the other JBO members. Anyway, add an intake to go with that combo of yours and things will work a little better. Other than that, Darkstars has the good idea. 4-2-1 header = low end torque. But also know this. A 4-1 long tube header = power throughout the entire powerband.

Yeah,
If you don't go custom, Pacesetter's header is about the only way to go for 4-1.
But for a little more torque midrange-low, go for 4-2-1.

FInally, you can't get around having a louder than normal exhaust with a header.
Just gonna have to get a longer resonator.

Remember....syringes go in the RED waste basket.
but does a resonator do any good with sound or not...people told me that it does no good...should i ditch the pacesetter setup and go along with like a magnaflow universal...would it fit into the stock location?
i say get carcustoms.net's engine mount kit, they work great for low end torque.
Resonators help get out the raspyness and muffle sounds and melow out the exhaust tones.
It will help

from personal experience and physics you'll get more low end torque by using the stock TB over the 62mm with an otherwise stock motor that is

I understand the engine mount princible...but the trade off of shaking the car apart...dont care for that part of it.
its really not to bad, i have the upper and lower mounts, stage 2 cams, and no more balance shafts, and yea the vibes are there but its nothing to get used to really, its not liek you have a cadillac hahah

I think what James Cahill was trying to figure out is how the hell engine mounts will help low end torque. Quite simply, they won't.

Absolutely. I recently got the DC Sports 4-2-1 header and it is incredible with low-end, and still really nice in the high-end, but it "fades out" slightly as you rev real high

Yeah, I have the Pacesetter and I'm pissed at myself for buying it.

Didn't get the "kit" which I assume includes both the upper and lower mounts. I got the Car Customs upper mount. It rules in the low end. I see James Cahill's perplexed response also, but really it does make for very crisp and deliberate response when you mash on the gas. I had a great experience with it. Sure it transfers vibration into the chassis and steering wheel, but

how much of a gain can I expect then from a upper mount?
Spotabee, good idea, except:

He's another N/A guy...

An upper mount will not accualy add torque. It will make your transfer of power more efficient.
The T/B will hurt your lowend but the gains up top far out weight the difference. Honestly you should look for more mid range to upper RPM power. Both the Eco's and the LD9's have great tq they just start to fall top end.

How is that Pacesetter catback? My friend has one on his Civic and it gave really good gains, and the sound is decent. However I have heard bad things about their quality... what's everyone's experience with them on the 2.2?
JH - the chrome tip is very nice, the sound though is not the greatest - as far as a gain on it with horsepower - my current at the wheels measurement with my current mods is 133 HP according to the dyno test a I had done @ 5300-5400 RPM.
the next guy in a 05 Mazda 3 only pulled 135 HP @ RED-LINE! my car though, I did not push it that far. - interesting comparison I though.
Interested to hear some feedback on that subject....if any!
the TB with no other supporting mods will hurt his performance 1/4 mile wise though
even when i had stage 2 cams and the 62mm TB i was .3 slower in the 1/4 then when i went back to the stock TB and stage 2 cams

car customs.net doesnt show their own upper engine mount, they show the rk sport...is that the one you bought?

Did you do any tuning to your car? If not you will deff not get the full gains you should have adding the Throttle body with those cams.

no no oppurtunity to do any tuning ill eventually go back to a 62mm TB after i do the head work and am able to re tune everything

If its low end torque you want swap in a v6.
small tips....j-body and overall....
-keep the intake runners long and the plenum decently sized, the longer the runners usually the more low end torque from velocity.
-dont use and oversized TB unless the engine has been modified to accept more end... adding bigger TB moves the power band to the upper end, cause you lose velocity down low...
(simply analogy is, the lungs -engine- still have the same capacity, opening your mouth wider doesnt necessarily mean you will increase the capacity your lungs actually use)
- headers.... stock is ok, headers flow better:
4-1 short tube top end... (pretty much the same for intake manifold style as well)
4-2-1 low end -mid range...
4-1 long tube low end and all through the band.... (same way as your current manifold is designed and why we have torque pretty much all throughout the poweband.
