Eliminator

I dunno I like the sound of my exhaust if its costing me a hp or 2 till the damn thing rusts out i am not replacing it.

Yep, I think the gain from the Flowmaster muffler alone is negligable. I stated that it would not DECREASE HP. The 160 degree thermostat and manual fan will add HP. I got a .2 sec verified gain at the track with these mods. The CAI is also a decent mod. If the car ran 13.9 stock (which is a damn good time for a stock LT1 Z, then yep, 13.6 would be a realistic guess.

From what i have learned online here..............flowmaster sounds good but it doesnt flow much cfm..............i think a cutout(obviously) or SLP two on the left flow the best...........but do what you want....its your car

well my white camaro had stock exhaust with , all those other mods i had except the gears, tranny had 2800 stall with a shift kit in it and a trnny cooler!! so after i put all this stiff in my car!! im hoping to be in the low 13's!!
i think my next thing is headers!! or should i get another exhaust right now or get a cutout?

DarkRider

you said it's 3 inch cat back right?
With a good set of headers, y-pipe and cut out(depending on how strict emissions is) you should be fine with the flowmaster.
I run the flowmaster right now - I am about to get headers and all that good stuff but point is I am going to keep the flowmaster.

When my 93,000 mile LT1 was still completely stock, running exhaust manifolds and a "Blowmaster", I went 12.82 THROUGH IT...With a full weight car

What are you running through what is essentially an open exhaust?

Don't bash a product just because of your poor driving abilities, or other problems in the car.

I have used Flowmasters on a couple of vehicles, and I love the sound. To me the sound is important, but it is a matter of personal taste. Flowmasters are very affordable compared to many of the other systems out there. While I have never seen any one actually post dyno comparisons between different systems, most say the Flowmaster doesnt flow as well as some. If you like the sound of the Flowmaster than just put a cut out on it for flow at the track.

Maybe flowmaster is loud at WOT.. but besides that it's certainly a shy catback compaired to my 2OTL.... I once had a friends 2000 Trans Am WS6 in my driveway.. and when he fired it up I didn't hear a sound.. all I saw was the tailpipes shake. Whenever I start my 2OTL up... you feel it.

That's because an LS1 w/ Flowmaster sounds pretty damn wimpy in comparison to an LT1 with just about any aftermarket exhaust.

I really like like the deep sound of the Flowmaster(as well as the 2OTL), but Flowmaster idles a LOT louder than the 2OTL or most other systems I've heard on the LT1...

As always(although most people never seem to understand this), what exhaust somebody likes all comes down to personal preference. What somebody might love, somebody else may royally hate.

Just go with what YOU like...

I was waiting for you to chime in

Anyway, I love my flowmaster, souns way better than my frinds who spent hundreds more and I can keep right up (and usually beat) them with no problem.

To my knowledge, no one has EVER showed a before and after dyno chart showing the flowmaster losses horsepower. Besides, if you're worried about horsepower losses, just get a cutout.

As far as a catback the Flowmaster sounds the best next to the GMMG setup and your spending half the money. Everybody wants to rant and rave about hp numbers and what flows better etc. etc. Who gives a sh*t about flow and numbers. The sound is what counts. That's probably the main reason we all get rid of the stock setup because it's not loud enough. I've been told countless times my car sounds better than others w/ the Loudmouth, Borla, etc. I know this not a fact and a matter of opinion but for those members on this board who are pushing 30 yrs old or more know what I'm talking about. 10 to 15 years ago nobody really knew who SLP was including Borla and a few others. Now a lot of people want to jump on the bandwagon because they see a new name and face. Lets not forget about Flowmaster and Hooker. Without these pioneer companies there wouldn't be an SLP, Borla, Corsa, B&B and so forth and so on.
