I agree if the exhaust is something incredibly obnoxious. I rolled down my window and could hear it all just fine...that muffler swap must be something fierce for DB level increase....most the time headers and a catback get what I would call LOUD. I could hear mine over the headers I had too.

 

Same here man. I run a shorty header, catless downpipe, and corsa touring catback, and I hear the blower just fine

 

Is his muffler that damn loud then?????

 

It must be. The air box mod makes the blower louder for sure, but nothing like an aftermarket intake will. My catless setup with header and Corsa Touring catback is quieter than when all I had was a GMPP manifold and GMPP Touring muffler welded to the stock catback (believe it or not). Most likely do to the size of the Corsa Touring muffler. It's a good deal larger than the GMPP Touring muffler. Also, Corsa resonators do a great job cancelling out unwanted rasp & negative sounds.

 

my muffler is pretty loud..and i have a catless zzp downpipe i still have yet to install so i may end up having to get a decent resonator..i gunned it today and really got on it in second and third and could hear it but heard my muffler much more lol so im sure that is the issue..i dont have a cel light comin on so if i didnt attach it properly that would have popped up for sure by now..what should I hit boost wise for an 06 ss/sc with the aem dryflow and a borla muffler (ie, not too much done in terms of performance yet)?

 

hey quick question to those who have put the aem dryflow filter in..when you installed, there is a rubber piece on the bottom that has AEM embossed into it. does that piece come off or is it meant to stay on? i was thinking since i didn't take it off, and it was supposed to, that would restrict air flow quite a bit and would solve my problem lol

 

That is considered the top of the air filter, and does not come off. You are thinking of an inverted top filter. Most AEM filters do not come with inverted tops. I think the air filter that comes with the SS/TC's AEM cold air intake has an inverted top filter, but it will not fit in the SS/SC's air box. Your filter is fine.

 

Ok great thanks!

 

I bet the big difference is the fact I have the CAI AEM kit and the box is removed completely.

Yes...Corsa Touring was my favorite as a DD. Others RIP and sound great but after a while I probably would've been tired of it on a long drive.

 

This.

I went from the air box mod to the AEM intake system, and I noticed it was good bit louder.

 

I would have to agree considering I never had a problem hearing the S/C once I put the CAI on. Windows up windows down...

 

yea i might just break down here in a few months and buy a cai kit..thanks guys

 

Dude, I've about had it with trying to do this Air Box MOD! I got the Right Filter(AEM) and I have the Air Box out of the Car and I cant get the Damn Filter to Mate properly with the inside of the Air Box, Every time I try and screw the Clamp on the Bottom of the Filter it Slips off the Opening at the Bottom! Are we supposed to cut a little bit off the opening, Cause I'm having a Hell of a time trying to get it to Stay?! If someone could let me know what the Hell I'm doing Wrong i would appreciate it, I'm Running out of Day Light, Thanks Joe

 

can you take a pic of what you have done so far?

 

Pete, Thanks for your wanting to Help, But Luckily I Figured it out, I NEVER Worked on a Vehicle before, I Mean the Most work that I've ever done was Chnage a Flat Tire! So, I gotta say I'm Proud of myself for doing this MOD and doing it Right. I Realize to a LOT of you this MOD is Freaking Simple and Childs Play, But for me its a HUGE Step. The SS Sounds Pretty Bad Ass Now and I think it's a Tad Quicker too! This is Perfect cause I should have my GMPP Stage 2 within the Next Couple of Days, Can't Wait!

 

no problem, and Congrats!
I still follow this thread since i created this mod so i figured if i could i would help enjoy!
Ironically AEM did dyno this type of mod long time ago and picked up like 6whp, lol so it does work, once you get the stg pkg it will keep the relearn down so it doesnt adjust the power back to stock.

 

Pete,

What do you mean when you say: "Keep the Re-Learn Down so it dosent adjust the power back to stock?" Thanks, Sully

 

the stock pcm is set so that the 205hp level is maintained. the stage tune eliminates this restriction. thats why the car doesn't make a butt-load more power in the cold than it does in the warm. it tries to maintain a set tq level cold/warm/mods or no/.

 

This is not correct.

The SS/SC did not have a PCM restriction that limited/maintained a certain power level like the SS/TC's stock PCM.

There is no "learn down".

There is a limit on the stock PCM for boost though, and that limit was held at the stock 12-12.5psi. That does not mean you couldnt make more power by opening up some restriction on the intake & exhaust side. It will not learn down the power increases like on the SS/TC.

Not to mention that 205hp level was crap. We all know stock SS/SC's dyno 210-215whp on average, and were underrated right out of the box. Meaning they should have been rated at 230-235bhp from the factory.

 

well then i stand corrected, I should have reworded what i said but it seemed to read correctly, basically yes there is not a "learn down" but what i meant is when you do the airbox mod, typically you will see a boost increase as well, thanks to the increased flow we saw an additional lb of boost, but we did find that after doing intake the stock tune did drop HP after time as the stock boost levels settled, the initial dyno was x and after 10 days with no other changes the car made less, with A/F ratios being the same or slightly different, then after addition of stage 2 the dyno power increased initially and after the initial pulls a week later.
But either way get the tune.

 

You are correct. You will see a slight increase in boost. This is due to moving the restriction from the intake side to the exhaust. You are now flowing more air through the intake, but havent done anything to the exhaust so the restriction will up boost a bit.

I dont know why you saw a loss in horsepower over time with the air box mod on the stock tune. The stock tune will not learn down the power. It will just limit max boost. That extra 1 lb or so of boost you saw did not increase power. The power was increased by flowing more air, and there shouldnt have been any loss in hp.

Youre right though.... A tune would be best.

 

So....Wait, I sure Hope it was well worth the $630.00 for the Stage 2 Kit that I'm about to recieve, Cause by the sound of both of your comments it dosent sound like it'll do much? I'm I right in thinking that? I thought that the GMPP Stage 2 would bring the Boost up to approx 15psi from the Stock 12.5? At least thats what I've read on this site....Thanks, Sully

 

Yes GMS2 will up your horsepower and boost. Average boost with GMS2 is 15psi.

We were talking about the stock tune. I was not talking about the stage kits.

 

Oh, Ok....Man you are Really Knowledgable when it comes to the Cobalt SS! Hey one thing that I just Noticed today, I was driving along and Floored it and saw that I Maxed out at 10 psi Boost after doing the Air Box MOD, But when I was Running Totally Stock it would Max out at 12psi-12.5psi Boost? Whats up with that? Thanks, Sully

 

I just put a cone filter in place of the stock filter and cut the box that the stock was in and its amazing how much more responsive it is. And cant forget the deep sound too
