i saw on the pontiac website two different exhausts on the 06... either a dual with bit 3.5" outlets or a dual-dual that says magnaflow on the side... is the magnaflow a dealer option and is it louder than the other stock exhaust??

the magnaflow come with the dealer installed autocross or appearance package that I believe runs about 3k extra

The exhaust on the SAP is louder, deeper, and more aggressive than the stock exhaust. The sound from the SAP exhaust resembles the Cherry bomb sound of the 1970's. The outlets on the SAP tail pipes are just under 3" in dia. Both exhausts are awesome sounding.

the autocross ones arnt that loud.... they pop a lot tho... I got um on my ride..I was thinking of making it straight pipes and taking the CATs out ... but I go race late at night and dont wanna piss people off LOL... :willy: arty:

no cats = federal law violation.

That aside, most of my buddies run without cats and its a raspy kind of sound.

I had received my GTO with the factory exhaust on it. After I had the SAP exhaust installed, I noticed it to be noticeably louder and more aggressive than factory stock. Yes it does Pop upon acceleration and deceleration just like the Cherry bombs did. I happen to like it. It's a retro sounding melody.

 

[Guest]

wonder if anybody has flowmaster's or dynomax on their ride?

 

[StarCaller]

exhaust? how you spell this?
straight through, that's the way to go......

 

[Guest]

sure, having your exhaust dump off the headers is the best way but.......thats LOUD.

I wouldn't recommend that, for a couple reasons,
1, it will violate the law
2. it will make your CEL go on, thus you would need the 02 imitator things
3. sounds louder, and you get more popping, and raaspyness, but not really a lot of HP Gain, also on a daily driver take a change on burning an exhaust valve,

I'd just leave them on, and spend money somewhere else, you'd be happier in the long run

You can get the Appearance pkg for about 2200.00 maybe less. Includes Frt cover lower extn, R&L Rocker mldgs, Rear bumper cover to accomodate the magnaflow exhaust with dual duals which is also incl in pkg. It comes to color in Quick Silver, Torrid Red and Black Metallic. It's also available in prime for quite a bit less.

 

[Guest]

not something I would get, adds too much weight.

 

[johnebgoode]

Mike are you referring to the Appearance pkg?

 

[Guest]

yeppers. All that stuff once added to the car adds weight when these cars need to be losing it !!!

 

[huskerGTO]

I've got Flowmaster Super 40's. LOVE THEM!!!!

I think they're louder and deeper than the SAP... just my opinion though!

[Guest]

Those are the 2 chambers aint they?

 

[huskerGTO]

I think so! :cheers

 

[Guest]

if they are louder than hell, thats the 2 chambers. Had those on my LT1 vette with 3" pipe and a 2800 stall. You could NOT carry a conversation at 60mph.

I met 1 guy with 04 and custom flowmaster's that turned down behind custom bumper don’t know what model but sounded really bad backfired when you let off a lot of popping and just plain loud! Now my new Magna Flow, they are sweet 2-3k sound is awesome and not too loud for old fart like me. I swear mid range is much faster. Just plain faster through gears,
