I was running a Gibson SS on my 2001 Screw until yesterday....I really liked it, in terms of fit and finish, but the sound was too quiet....

I replaced the muffler with a 40 series Flowmaster (2 chamber) and brought the truck to life....It's not too noisy, but throaty and aggressive sounding.....I stayed with the 3" SI/SO system, using the Gibson 3" pipes.....what a difference.

I also noted that there was seemingly NO LOSS OF TORQUE at low end, or at least it was so minimal that I could not decifer it.

Mike from Performance Chips says that flowmasters are junk and reduce low end torque....wrong!!! I do admit that my last truck lost some torque, but I had the SI/DO system with 2.5" tailpipes...but the sisgle out 3" system works great.....

BTW, I have an almost new Gibson muffler for sale if anyone is interested....it is in perfect shape and was on the truck for 2000 miles..........

 

I did the same thing but went dual out with the flow's delta 50 & I lost major power. I did keep the pipes at 2.5" all the way back to retain low end but no such luck.I now am back to my Gibson s/s. Oh well,glad you like it.I bet it sound's better.

 

Actually, I really wanted the twin tailpipes, but that is what caused the lack of power on my last truck....

That's why I went with the single out 3" tailpipe...it really did make a difference. Actually, I was told about using a single tailpipe by a guy that races Chevy stock cars....everyone else at the local dirt track runs open headers, and he adds a single short tailpipe to retain torque....works great.

I guess that's why the Gibson SS runs so good....If it made a little more sound I would have kept it on the truck.

I just ordered an Ariaid intake system, and we'll see how that works with the Flowmaster.....let you know!!!

 

Not really important for you now, but I've had my Gibson SS on for about 8-9 months now, and I've noticed that it has a bit more rumble to it now. Not sure why, because there is not supposed to be any type of "packing" inside, just baffles, but it's definitely "louder". My wife drove it one day, and I was standing in the driveway when she left. Boy, it sounded good when it took off. Not like some of the "bubba" sounding trucks that are around my neighborhood. Man, I hate those......

Stll, a very quiet system compared to others. But that's what I wanted.

Glad you like your new setup! I'm sure it's not "bubba" at all.

 

Mitch, The guy at Gibson told me that you could turn it around to get a little more aggressive sound. I don't know if it work's or If anyone has done it . Mine got louder with time also.

 

Thanks FALLSCREW. Yeah, I heard about that too, when I was originally researching what system to get.

Basically, I think it said that it would be louder, but also would not keep the proper amount of back pressure, so low end torque would not improve or even be less.

Since I wanted more low end, and quiet, I just installed it the normal way. Besides, it's all welded in now anyway.

 

=======LOL, that is too funny of a comment.

AND I know what sound you are talking about too!!

 

I'm sure you know what I mean..... There is a "good" sounding V8 exhaust, and then there are those that just sound like crap......

When you can hear someone over half a mile away (going up a hill in my area), and all it is is a popping and raspy noise, waking an entire square mile area up (he's doing this at 5:30 AM!!), that's totally "bubba" to me. Probably some POS chevy with glasspacks on it, but still, WHY would anyone want something so loud!

I'm sure I'm just considered "OLD", but that's not "performance" to me at all. All it is, is plain RUDE.

I would like to talk to about the gibson ie price. Can you email me at

Thanks, Chris

 

Hey Mitch,
That wouldn't be the hill by the fair grounds, don't most of those
yahoo's live out by bonney lake hehheee

 

From what I just read, do you guys think it's better to go with the single side out vs the dual rear? I was going to go with the Flowmaster duals but I don't think I will go that way now. I want some sound, and I don't want the "bubba sound" either. There is a guy on my fire dept with the "bubba sound" on his Chevy. And when he goes up the hill infront of the fire dept at 3 am, all you hear is the terrible loud sound, and he isn't going very fast. But anyways, i was thinking about going with the Borla. I had it on my V8 SHO and it sounded great. So do you think I go with the singe? (single, the story of my life) Or do I go with the duals? I heard if you are going ot pull a trailer, you should stay away from duals. ERic

 

I guess it depends on how much sound you want...the flowmaster 40 series (2 chamber) is a little throaty but not BUBBA, while the 50 serice (3 chamber) is a lot quieter, but louder than stock.

I have found over 15 years and 4 trucks that the single out system provides more low end torque....the dual out (typically 2 1/2 inches) relieves too much back pressure, allowing a slight decline in low end torque...it's not the end of the world, but there is a noticeable difference.

Either the dual out or the single out have about the same level of noise, though the single out might be a tad quieter.
