hmm... just what the topic says. im kinda curious to know which exhaust flows the best, and which one sounds the best... and if there are any that flow really good and sound realy good as well. im not gonna go out and get a shtty *** exhaust that flows awesome, or buy the best sounding exhaust that flows like sht. just looking to see if anyone has any real info on the best flowing exhaust.... best sounding would be your opinion, but im still curious so lemme know so i can figure out what i want already, lol, thanks guys

 

borla good sound good flo a lot of money

loudmouth good sound good flow decent price


i had loudmouth and sold it for a borla

and i love the borla

 

yeah, i like the way borla sounds... but i heard magnaflow has the best flow. how good do they sound?

 

I have Flowmaster they are great sounding and good flow..... however if you have the money I would go with the Borla i really don't know what they sound like but I love the flow they have... still think Flowmaster is the best sounding so far..... by the way LT1 & LS1 sound diffrent even using the same muffler on both....

 

i heard it and it sounds ok....but my borla with headers sounds too good to be true.......

 

Flowmaster is anything but the flow master!!!!! It flows like crap on an LS1!!!!!! Get true duals, or do the dynomouth!!

 

i dont think flowmaster is that bad

 

As far as catbacks go, the LoudMouth clearly flows better than anything else and is lighter. It sounds great with the stock y-pipe and cats. Without cats or with long tubes it is VERY LOUD.

I have the Hooker catback on my T/A and really like the way it sounds with FLP's and cats. It was pretty loud without cats but still sounded awesome.

 

What about SLP 2 on the left exhaust? Thats what I have and it seems to have a SOTP feel to it.

 

i have SLP loud mouth with SLP headers and a high flow cat, my car is extremly loud!! it sounds good but its loud! i thinking of adding a muffler or something else to quite it down.

 

The SLP 2OTL is another great catback. I used to have one on my old '98 1LE. They are stainless, priced reasonably, deep but mellow at idle and sound great at WOT.

I would not use a LoudMouth behind anything but the stock manifolds, cats and y-pipe.

 

Go with the SLP Loud Mouth

 

Actually for where you are planning on going, either 3" duals with bullets dumping before the axle, x-pipe, and LTs. Or a 4" mufflex with LTs and an ORP.

 

Dynomouth.

Flows like the LM.
Costs much less.
Sound cannot be touched by any other cat-back, except possibly duals.

Some interesting flow numbers obtained from LS1.com:
Borla- 900 cfm
Magnaflow- 1100 cfm
Flowmaster- 350 cfm
DynoMax bullet (Dynomouth)- 2200 cfm
Loudmouth- 2200 cfm

 

I like the QUIET approach.I have the Dynomax race-welded cat-back and it flows about the best of any muffler out there.I don't remember the exact numbers,but all the muffler is,is a y-pipe surrounded by fiberglass.Some people don't like it because it's not much louder than stock.Although it is mucj deeper sounding.
