Flowmaster 40

[streetg1202]

what do you guys know bout Flowmaster 40? is it pretty loud? i just want a low deep "rumble".. not BRRRRRRR ykno? :D

[jabartram]

I have a single 40 series on 2.5 inch pipe and people tell me that it sounds like a V8, and I love the sound, it does get a little toney at times, but that is to be expected!

I have A Flow 40, but i have the 2.2 ecotec, even my exhaust has a drone to it with this muffler, and the tone is much much deeper than that of my freinds with the 2.2 eco and phartcans. I really like it. Turns heads :P

PPl are like "wtf is that noise that alero?" its great

[streetg1202]

are all Flowmasters stainless steel? i was looking through some and it doesn't specify wether they are SS or not.. don't want to get it and turn out they're almuminized.. also does it matter what part # i get? or are they all same?

[jabartram]

Flowmasters are aluminized, but I haven't heard of anybody having any problems with rust, and I live in south Texas on the coast!

[BLK03GXS]

flowmasters are aluminized, however they will last forever, but the seams will develop surface rust, all you need to do is get some high temp clear coat :thumbsup:

[streetg1202]

high temp clear coat?

[streetg1202]

only one i cand find around here is for 550.. dun think dat will hold on exhaust.. are there stronger ones available?

[mobs241]

you think the block has less heat than the engine?
exaust heat is only around 400 degrees

[streetg1202]

lying punks at NAPA :evil: .. they're tellin me i need like 1500 degree clear coat.. so i can just get this 550 degree thing and just double coat it or something?

[Youngblood77]

If the exhaust heat is @ 400 degrees, then why wouldn't that 550 degree stuff work? :blink:

Give that 550 degree clearcoat a try.....it's only 5-8 dollars a can, and what's the worst that can happen? it burns up and flakes off......

[streetg1202]

they were tellin me exhaust will heat more than 550 degrees... but yea ill give it a try thx all

And no, they're not all the same: there are usually at least 3 variations of each series of muffler, and within those variations, different inlet/outlet SIZES.

For example, 3 different delta flow 40's, 3 different origional 40's, 3 different 80's, etc. etc.

The different numbers are for mufflers with different inlet/outlet locations and sizes. If you look under your car, try and picture a flowmaster muffler in there instead of the stocker, and that will help you determine where your inlet and outlet should be. Next is to determine what inlet and outlet size you will need......are you changing any pipes in front of the muffler? If not, I think the stock piping is 2".

hope this helps

[streetg1202]

thx youngblood :thumbsup: is the stock 2"?? i already ordered 2 1/4".. hmm maybe it'll work out.. not much diff.. thx again.. im new at all this.. tryin to do it step at a time :P

[bigd6983]

ours is 2 1/4 and aslong as you ordered the offset in/center out everything will be cool.....

[streetg1202]

dass good news.. dass wut i got.. and ill go and buy this 550 degree clear coat thing and see how it works after like 2 days (since it rains here in GA everyday >.<).. thx for all ur help guys will let u kno how it works out

[BLK03GXS]

Well i havent clearcoated mine, and i put it on in the winter (i live in BC Canada), it rains lots here too... and mine isnt rusting at all.

[GLSalero99]

I had flowmaster 40's on my old cougar for years and had no problems with rust, except where i'd bump them on the ground (bad suspension stuff) and to fix that I just spray painted them, never had any problems.

[streetg1202]

forreal? well 2/2 says no prob.. dun need to spend extra 10 bux if i dun need it.. im plannin to just get a tip from Advanced Auto parts.. like 20 bux SS tips.. will it be okay to do that?

[Youngblood77]

If you like the style of the tips, then go for it man, I'm sure it'll look great ! :thumbsup:

[Youngblood77]

Hey '03......are you running a single 40? Any other exhaust mods? How's it sound? After I get my hands on a set of springs, and some tint, this sounds like the next mod for me......

[streetg1202]

[Youngblood77]
