Flowmaster Super 40 Muffler, Welding needed?

OD Ram · Oct 24, 2012

I have a bone stock Ram 1500 ST 4.7l. I'm going to change the exhaust on it and want to know a few things. One is, once I get the old muffler down, will ANY welding need to be done? That is my main concern at the moment. And could I utilize the rest of the muffler (coming out of the old exhaust) on the new one?

Thanks,
OD Ram

The one I plan on getting: Flowmaster 953048 Super 40 Muffler - 3.00 Offset IN / 3.00 Offset OUT - Aggressive Sound : Amazon.com : Automotive

it's loud, i had one on my last truck, and the people across the street though my truck was a diesel, not sure how.

I don't know what the muffler on an 03 looks like, but I have a 2012 1500 5.7 and I know my stock muffler was fricken huge compared to my flowmaster so he just welded the muffler on and then added the extra pipe needed to compensate for the lost length from the stock to the flowmaster but even if the stock and flowmaster were the same length, yeah my best guess is that the old muffler will be cut off with a cutting wheel and the flowmaster will be welded on plus a new piece of pipe however long to compensate for the lost length.

I know my OEM muffler is huge. There's a guy in town that runs a pretty good shop. I might just have him do it since my knowledge of welding is nonexistant. Also good to hear that it's loud. I want it to be. Unfortunately my state doesn't allow straight pipes.

if you want very loud, almost straight piped, get a flowmaster 10. loudest one they got

It can be done without welding but in the ling run its easier and more durable to just weld it.

I do my own welding, I surely say a good weld is better than any bolt on flange or clamp. I'm putting a Delta Flow Flowmaster 44 muffler on my 4.7. Pics posted when done in the next week or two. I want to keep interior noise down a bit, and have decent back pressure. I love that my 08' has 3" stock exhaust already. Just gonna swap the muffler in with a small section of 3" pipe added to make up for the difference in length of the super long stock muffler.

Looks like I'll just take it down to be welded by the sounds of it. Or buy the clamps, do it myself, and get it welded at a later date (may not have enough cash as I want this fitting in 2 weeks). And I would actually love to get Flowmaster 10s, but I'm not sure they are legal in Florida. There is a noise limit here.

It's a bit less noisy than straight piped.

And half te price of a 40 series

OD Ram · Oct 25, 2012

But is it legal in Fla? That's what I can't seem to find info on. There are certain regulations here compared to Texas or NC, it's the reason why I can't have straight pipes. I can't imagine a muffler that is so similar would be legal.

TheMaddog · Oct 25, 2012

It still has chambers, like a normal muffler, but is just really small, which gives it it's loud sound.

OD Ram · Oct 25, 2012

I'll try to get my hands on it if it's legal. I don't want to get a ticket for noise disturbance.

KGBIGCOUNTRY · Oct 25, 2012

The single chamber 10 series is loud but still semi tame with the cats on the truck. Around 2500 there is a werid transition sound in the note below 2 below is ok 3 and above is pure sex. Im running a Jones Exhaust Full Boar which is the same as a Flowmaster 10 series. The case length of the muffler is only 6", overall length is 12" and its a single in single out.

OD Ram · Oct 25, 2012

Nice. The muffler will work just like that but without the full system correct? I now it's probably a stupid question but no way in hell do I have enough cash for a full system at the moment.

TheMaddog · Oct 25, 2012

Yep. You already have cats on. So go on and do it.

Mgpatton1s · Oct 25, 2012

That's what I did, I know a guy that owns a Mr. Muffler, the muffler was 150, he charged 50 for labor not a big deal. I could have done it i would've had my mig welder at the time but I just had a plain ole stick when I got it so I figured it'd be easier, more durable and less time consuming if a professional did it over me lol
