I'm looking at buying a 1 year old used flow from a guy. He doesn't know the model, and the only number he can give me is the pat # 4574914 (4.574.914)

I've tried researching and looking around to no avail . Anyone know what model Flowmaster this is?

 

Looks about the size of a 40 series, most likely DeltaFlow or Original. Super 40's tend to be black from what I've seen/have. See if you can spy heat marks from the baffles inside, 2 = original 3 = delta . . . I don't know why flowmaster doesn't print the model on the cases.

 

They laser on the part number on the inlet face side.......so in the pic, the number will be next to the inlet, opposite side of the end of the case.

That number listed is not a flowmaster part number......all flowmaster muffs part #'s start with a 9 and has 6 digits, except the dual outs. The Original 40's, which start with a 4 and has 5 numbers.

I'd say you definately have a 40 series of some sort....doesnt appear to be a Super40. I vote Delta Flow 40.

Grab the number off the inlet end of the case, and post it up. Or look it up on ebay or flowmastermufflers.com.

 

Yeah, its not in my possession yet.
The guy is at work so i wont be able to get the number until later.

If i had the actual number i could tell what it was, but thats all he gave me.

 

That is a 40 series Delta flow. I have a pair of those in my garage and that is the same number on mine.

 

By the looks of it, its an original 40. And the super 40 is black, but the paint slowly dissapears.

 

Yea....my super40 didn't look black a year later. lol. It's a 5x10 case, and i believe the original 40 is also a 5x10 case. And my Super44 that's been on for like a month is already losing its paint.

 

The number he gave me was 42543.

Which when i goggled it turned out to be a Delta 40.

Now do i buy it for the $25 or pass on it?
Its about a year old.

 

942543 would be a delta 40. 42543 is an original 40. cheap enough...do it.

 

$25 is nothing for a flowmaster, i say pick it up and put it on
