I have Magnaflow on mine. I like it because if your just cruising its not very loud in the car but if you get on it you can really hear it.

click on the links in my sig. you will hear it when it has a cam with stock manifolds cats, and the LM

another one is with cam, LT's/ORY and LM

another is cam, heads, LT's/ORY and LM

just click on my user name and you will find all 4 clips of my car in various stages. this should help answer your question. also check out and listen to clips on: www.ls1sounds.com

Loud Mouth for sure. The stage 1 (that I have) is very loud. Stage 2 was toned down so if you like the Loud Mouth but want a bit less WOT noise, get the stage 2 catback.

SLP Loud Mouth is the only way to go. Stage 1 is mean and will wake the neighbors. It really lets you know you have a muscle car. The only thing different in Stage 2 is about a half inch of baffles in the resonator, it lessens the drone at 2500 RPMs crusing and tones down the throaty sound of the exhaust, but its still pretty mean.

Nothin like letting everyone know your coming from 8 blocks away...

Borla catback best way to go!!!

I have the LM1 on my SS with stock manifolds and really like it, despite some drone at 2500 RPM or so. Probably one of the best sounding cat-backs if you are running stock exhaust manifolds.. If you have headers or plan on getting them later, then I think the Magnaflow is your best option. The Magnaflow has a mean sound with LT's. The LM is too raspy with headers, IMO.

If you plan to keep the stock manifolds and cats, the Loudmouth makes a great catback for tone.

If you plan to remove the cats and add long tubes, avoid the loudmouth like the plague or your car will adopt several nicknames you won't like, i.e. Truckmouth, farmtruck, and people will duck when you drive by because it sounds like a machine gun is being shot off.

I ran the Longtubes+ORY+LM1 setup on my previous vert so I know this from personal experience. It sounds obnoxious and you will catch way too much attention from law enforcement.

You got a good deal, now sell them individually and make some money off of it all and buy a better setup

Yep! what Y2K said!!!

**SiggyZ** · 04-16-2007, 06:42 AM

Or you could replace the resonator with some bullet mufflers to lessen the rasp. Either way, I would also ditch my LM if I were to go to LTs.

really? i have only caught thumbs up, and compliments from people.

only great thing, is that i scared some smug dick driving his Saab, talking on his phone with his window down, driving slow and not getting over. when he did change lanes, i dropped into 2nd gear and punched it. scared him so bad he tossed his phone out the window and i just kept on going...

Magnaflow. Hands down.

I had the SLP headers and the Loudmouth. I ended up cutting it off it sounded so bad.
