ok...im keeping stock manifolds, maybe upgrading to high flow cats. Now the question is what catback to buy. I was thinking magnaflow for a nice stainless system and then having a cutout on the i-pipe. or what about just having the slp loudmouth. im between those 2 choices....magnaflow and cutout or just the loudmouth. let the voting begin.

Magnaflow all the way ive had them both, on stock manifolds and headers....magnaflow gets my vote hands down!!!!

I would have to lean towards the magnaflow never owned one but have heard them and they sound badass.I have owned a LM and it was okay until i did headers and ORY and then "FORGET ABOUT IT"

how loud is the cutout going to be if i get that with it...a lot louder than the magnaflow?

Yes. It's much louder when uncapped.

Axltransam

All hell breaks loose when they're open. They make my car sound like it's ready to enter in Saturday's Busch Series Race.

Axltransam

so u are reccommending 2 or no will 1 be loud enough. if u reccomend 2, where did u place them, do u have any pics

Axltransam

whoa...disregard...i just checked the link. what size cutout do i get for a stock i pipe. is the i pipe before or after the cats.

SouthFL.02.SS

1 cutout is plenty fine. 3" in the I-pipe in the undercar well just behind/under the passenger seat- you'll see, it's the perfect niche for the cutout.
Manual cutouts are cheap- $40, but getting under the car to uncap it gets old. Check out QTP's elect. cutout. Flip the switch and it's loud when you want it.

Axltransam

so the i-pipe is before the cats

SouthFL.02.SS

No, the I-pipe is the long segment of 2.75" diameter (stock) exhaust that connects the Y-pipe (where the cats are) to the Catback behind the rear end.

If I am not mistaken... A cutout with loudmouth will just be louder in the car. loudmouth does not have any resonators or mufflers so it would not make a difference. Magnaflow...maybe since it does have a muffler and a resonator I believe. Please correct me if I am wrong. And this young man claims he is going to stick with stock manifolds so the Loudmouth will be louder.
Comparing the magnaflow and LM with stock manifolds, the Lm will be louder. Anything with mufflers or resonators will not be as loud as a system without that ****.

or go true duals dumped before the rear axel! that sounds mean as hell with stock manifolds!

LM has a small resonator.
Magna is a standard, 1 muffler catback.
I think this guy is asking about the Magna/cutout combo vs. the LM w/o a cutout.

The i-pipe is after the cats, right under your passenger side rear seat. On another note, I have SLP longtubes, ORY, cutout on the i-pipe and the Magnaflow S.S. catback on my SS. I like this setup a lot because it has a nice tone when it's capped up, and then I can uncap it when I want it to be really loud. I had a QTEC electric opener on my cutout and would not recommend it. All I had was problems out of the QTEC opener, while my friend who bought a McCord electric opener has never had one problem out of his.

southflo2ss is correct with the combo that i am looking at

Magnaflow S.S. catback with a cutout would be better than the Loudmouth IMO. The Magnaflow 3.5" tips look a lot better than the SLP dual-dual tips too.

I have the Lm and the resonator is fake...
