CAI, Headers, Exhaust recommandations....

[Lefix]

Hello, Im new to this forum, and i been reading alot of threads and i have some very simple questions.

I own a 2005 Pontiac Sunfire 2.2L, i want to buy a CAI, and exhaust, and is header really THAT important?

I want to buy a AEM CAI:

And instead of a complete cat-back exhaust kit, i was wondering if i can just get away with two decent mufflers, lol... (cuz i have a sport package when i bought my sunfire, it came with two exhaust pipes)

I was looking at this muffler, Tenzo R Venturi universal mufflers:
http://www.andysautosport.com/pontia...z00091270.html

Is that muffler any good? If not, can someone recommand me another brand or something?

And one more question, is header really that important? If so, can someone link me to a trustable site that i can get a decent/good header from, i was reading through some threads and i heard that the pacesetter's header were decent, but if header is really that important, then i might buy one too...

So can anyone answer my simple question? Very appreciated

Cheaper CAI

Header depending on what you go with ( 4-1) ( 4-2-1) will def. make your exahust upgrades more noticeable. I have a 4-1 and it made my top end faster. But i can't really compare since i did a whole new exhaust setup from header back on the same day with dual mufflers and 2.5" SS piping.

That muffler is way over priced. Stay away from andy's autosport. Look at Jegs, summitracing, Gravanatuning, Aplusperformance, turbotechracing. The prices from these guys are a little more fair.

Oh wow, so AAS is crappy? I always heard that they are REALLY good, lol...
So what do you think about those mufflers? Is Tenzo R a good brand? I don't know if i should buy an entire cat-back system, because if i can only do the mufflers, then i would rather do that. Are the pacesetter headers any good?

Oh and i think AEM CAI's are better than those GM ones... And the AEM are only 250....

4:1 is better or 4:2:1?

[Classicrocjunkie]

I have a pacesetter armor coated one myself. I love it.

AEM is a good brand, however your paying out the ass for a brand name. The one i listed are actually ones a local shop around me produces. I work at that shop from time to time to help out with odd jobs. My entire exhaust and intake setups were all done by them. Its all stainless steel and not aluminum like AEM.

It all depends on how much money you want to spend man. Look into Megan Racing cat back on Ebay. They are good quality and are around the price of 2 of those tenzo mufflers you were lookin at. You'd just be down to 1 muffler .

Cat-back on ebay

[DeadBlade89]

I would personally get a cat-back over just a muffler to get more flow overall which would gain a little more hp in the end. look into magnaflow, borla, and vibrant for cat-backs.

about the headers, 4:2:1s are alot harder to find then 4:1. I dont believe i came across a singe 4:2:1 for our cars when i was shopping around. the difference between the 2 is this: a 4:1 give u better gain in the high end and 4:2:1 gives u better gain in the low end. its souly on what you want, no one is better then the other. and yes, pacesetter is one of the top brand makers of headers. very good quality.

about Tenzo R, they arent a bad brand but they arent great either IMO. start a thread or search the forums and see if you can find anything more about them.

I think im just gonna get the AEM CAI, and two Mufflers and have a shop wield them on.

How about the magnaflow mufflers on summit racing? They are about $120 each...there are so many different ones and i have NO CLUE which one is good or bad lol...

Theres these Street series, and race series, which one should i get?
What are the race cores for that are inside the race series?
There are 5" x 8" oval, 5" round, 6" round, and 7" round, are they mostly the same beside the size?
Is the oval better or the round ones better?

I was looking at these from Magnaflow.com, and they are $213.08 each, Summit Racing is selling them for only $111.95 each.

Are these any good? Will they make a deep-toned, non-fart can sound?
These are double-walled, is that better than the single-walled?

[Classicrocjunkie]

Magnaflow - 14832

2.25" inlet
4" outlet
14" long
5x8 Oval body

$91.95 @ summit

$91.95 @ Cardomain Store

This is what i am running, summit never seems to have these instock, so i ordered through the Cardomain store site.

[Lefix]

How do they sound? Are they deep? smooth? Non-ricey?

And what is the difference between 14829, 14827, 14832 models? Are they just different in length of tip?

Would you get the 4" tip over the 7" tip?

[Classicrocjunkie]

Pretty much thats the only difference. I wanted a short tip since i knew i would be in a crunch for space under the car. I wanted to be able to see the mufflers and not have to push them too far under.

Before i added a resonator

If you just adding the mufflers your stock resonator will be fine. I did a whole new setup from the header back as you can see.

Pretty much sounds like a turbo'd car exhaust right now.

[Lefix]

Wow, thats really good, since i have a sunfire, that means mine should sound pretty much the same then? Im gonna buy the 14829 model because i dont want to show the muffler, and that should sound the same as the 14832 u got there right?

[Classicrocjunkie]

Should sound pretty good. Won't be exactly the same since i am running an aftermarket header and 2.5" exhaust piping.

Will sound more like this does, just ignore the music thats playing in the car

[Lefix]

Lol, is the second video suppose to sound better than the first one? and is the second video your cavy after the header and resonator?

One thing tho, my sunfire's mufflers are 20 inches long and has an 8 inch tip, the 14829's that im gonna get is only 14 inches long and has an 7 inch tip, will that work? I need to add little bit piping right? And does the 2.5 inch piping sound better than the 2.25 inch ones that are stock in my car?

[Classicrocjunkie]

The first video was my car after the install without a resonator.

The second one was my stock exhaust and a plan 3A racing muffler.

Just get some muffler shop to install them for you. If they charge you more than $25 per muffler go some place else. The new shop should make a custom mount to adapt to your old one and add any extra piping you may need. Your stock exahust is 1.75" give or take alittle bit.
