Random questions about headers and exhaust

[WildDuece]

Okay i have two choices for a header, one is a 4-2-1 pacesetter and the other is the 4-1 RK sport. i did search and could come up with no reccomendation for a 2.2/2200 j body. also, does anyone have a recording of the RK sport cat-back exhaust and/or magnaflow? or can they just describe it? im looking for a lower rumble from the exhaust, and trying to avoid the F-1 racecar sound.

these are the parts im talking about...

Just an FYI, you install a header your exhaust is going to change dramatically sound wise. I ran with the Armor coated Pacesetter 4-1 and a one off 2.5" header back exhaust 2.5" high flo cat, 18" magnaflow resonator, and dual Magnaflow oval mufflers.







Disregard the rust... : Looks for sand blaster online:

Here are some sound clips.

Its very very deep toned ( that slight rasp was because it was a cold start up, when its warm its not there)

thanks. any one know about the sound on the rk sport exhaust? and yeah. ive noticed most cavs and sunfires have that rasp while they are cold...

RKsport sounds like shit without a resonator. Buddy had it on his old Z

Cant you just get the resonator deleted? What exactly does it do and what is it lol, I have never figured this one out.....someone told me to get rid of it when I get my exhaust done.

[Classicrocjunkie]

Resonator gets rid of the rasp in an exhaust. If you install an aftermarket header it changes the sound of the exhaust dramatically. I didn't add one when i did my exhaust at first, but i got really sick of the sound when i got into the throttle and all i heard was a can od bee's. If your boosted you can get away with not having one, but N/a sounds like ass.

Ahhh, how much is one and whats the best/cheapest to go with?

The RK Sport / Magnaflow Single Muffler Cat Back Exhaust (Magnaflow PN 15761)

Driving Around With It On The Car
Once installed, we started the car, and the sound of the engine running at idle was totally imperceptible, even in a quiet, residential neighborhood. The tone was deep, but could not be heard unless a person knelt down beside the exhaust tip to listen.
This was rather disappointing, as we expected that big chrome muffler and big chrome tip to emit a more noticeable sound at idle speed, as opposed to sounding quiet to the point that a driver in another car might pull up next to a Cavalier with the RK Sport / Magnaflow exhaust at a light and assume the car had nothing more than a chrome muffler and tip on the stock exhaust.
The exhaust sound above idle was a bit more noticeable, but not as pleasant as would be expected.
From about 2,000 RPM through 4,500 RPM, the sound is only slightly deeper in tone than a chain saw. Lenny seemed more upset with this than anyone else, saying his car sounded like a rice car. We didn't think it was quite that bad, but not as deep a tone as we are accustomed to with Magnaflow mufflers.
Lenny also commented that the exhaust was loud at highway speed when he ran the car up in gear, and that the tone at higher engine speeds remained higher in pitch than he desired.
We attribute much of the higher pitched exhaust sound as being caused by the smaller, 2 1/4 inch diameter of the pipe, which is too small for an engine of this size, and the angled walls of the exhaust tip, which do not result in as deep a tone as tips with parallel walls.
Lenny also commented that the car did not feel as strong with the RK Sport / Magnaflow exhaust system as did the stock pipe with his loud muffler. A little better than stock, but not a lot.

The Iperformance Cat Back Exhaust

Driving Around With It On The Car
The Iperformance cat back exhaust system had a more noticeable sound at idle speed. It was not overbearing, and was about the same volume as the original equipment exhaust, possibly a very little bit louder, and very deep in tone. It was very evident at idle speed that the car did have a performance exhaust system on it by the tone.
The exhaust sound is authoritative when the engine is above idle speed. It is deeper in tone than the weed whacker import sound and also noticeably deeper in tone than the RK Sport / Magnaflow exhaust.
Lenny was grinning from ear to ear. He said it was a little bit quieter than his loud muffler on the stock pipe, but that the car felt like it had a lot more power.
Lenny also said it sounded very good on the highway and that the car felt like it pulled much harder.

my cavy sounds almost the same. yours is a little deeper but not much and all i did was go to the local auto parts store and bought a glass pack and it gave me about the same sound for a lot less.

by the way both youalls cars are frickin sweet. they are both beautiful works of art. and people think cavies are little pieces of junk
