duals or single

i do not want to loose any of my bottom end ... i want to gain bottom to mid with improved gas miliage... i dont know if its possible but i figured i tell you want i wanted

i would like a nice deep sound but, not overly loud in sound...

last night i was with a couple of buddies that i ride 4 wheelers with that went to different school and they introduced me to a guy that had a bad azz chevy it had everything i wanted on mine... besides the 6 inch lift .. he only gets 12-13 miles per gallon... (not good)

but anyhow on the flowmaster site 50 series sounded like crap... but the 70 series sounded good...

well on this guys truck he had single 50 series and it sounded great... much better than the site. but it was already installed on his truck when he bought it so he couldnt tell me if it helped it any or not...

then last night i went to Avalanch.com and they said they had really good luck with gibson single ... and it gave them more low end and mid range and had no promblem pulling...

then there were these guys with dual flows that said they pulled better with stock pipes... and thats not good...

i am really confused to what to get cause i dont want single all that much because it single... and duals straight out the back would be awesome looking but i much rather have performance i suppose..

so do you think i will be happy with 50 series single inlet and outlet mufflers ...

they were on ebay .. and i will get them for like 50 dollars i think...

can someone help me out my head is spinning to hard...

I'll give you my opinion on this, but remember that it's MY opinion...others may feel differently.

In general, you will probably experience better performance with a high-flow muffler and a single pipe out that's mandrel bent and about 3" in diameter. The flowmasters are decent in flow metrics, but there are others that flow more...again, thinking about performance only and not the sound. If you're going to tow very much, pipes that exit straight out the back are not recommended.

On my '99 ZR2, I have a FM40 non-deltaflow with dual 2.25" pipes and 3" tips. I like the sound and the performance is satisfactory. I may have lost a little low-end torque but I didn't notice it.

When I bought my '00 Sierra, it already had a dual exhaust which sounded pretty good but had really large tips. I ended up replacing the dual pipes with a single 3" mandrel-bent pipe in the stock location with a 3.5" tip. Looks cool, sounds good, pulls a little better.

It's basically deciding which you want more, performance or cool looks, and then making some compromises if you have to have both.

Good luck!

Most quality aftermarket catbacks or high flow mufflers will produce more hp and tq, but at higher rpms. You WILL lose some low end grunt, so if you tow heavy loads, stick with a single 3 inch mandrel bent pipe.

I personally wouldn't go with a flow 40 on my truck, I think that they are much too loud to drive around with everyday. They draw to much attention when you romp on the gas. I'm really want the gibson supertruck setup but I have heard that they are obnoxious as well. If anyone has heard the 40 series flows and the supertruck exhaust let me know how they compare noise wise. I want something aggressive but not real real loud.

to be honest i cant really hear mine in the cab. i got the jones muffler pipe 2 into one. i heard it on a 350 and they had another 350 with true duals beside it with flowmaster . and i likes the one that was on the other one so i told them to put jones on my truck.. its sounds pretty good when you start it up then the sound dies out. then when you get on it you can hear it. if i have it in 3 drive around 50 it makes alot of noise. i think it sounds pretty good.. but if i floor my truck you hear more motor than you do my new muffler set up .. i am planning on getting headers pretty soon .. thanks for all your help and opinions.. i sorta didnt get what you all told me i just got what i heard and liked.. but if i were you i would give jones a call .. sounds really good to me . i dont think it helped in mpg.

but i think it added more bottom end power along with some mid-range..

casue i used to be able to spin tires at the school parking lot .. but no smoke them off like i am now..... but it could have been a number of things.. cause its got cold and when i first got my truck i was really easy on it..

i am starting to get really easy on it again .. its hard though... its fun when you sit your passengers agaisnt the seat when you take off ..

or surprise someone that your fullsize truck can get a wheel.

Maybe you were being too easy on it or something, cause I can smoke my tires on my stock 5.3 at the drop of a hat! The way every truck should perform!!
