Need pics of Flowmaster installs on 3.0 Engines

[rennch]

I'm doing a Flowmaster 80 Series (a la Jack) for my RSR'ish conversion, and I'm probably taking the car next week to the muffler shop. I want to come armed with good pictures to give the guys so they know how the install is supposed to go. It would be a dual in/dual out install. 3.0 motor with early headers. This is what I've got at the moment:



Thanks all...

I should mention that I have already notched out the RSR bumper for the tips...

I'm not sure if this is the same, but the Magnaflow I have is set up this way. Primary tubes dump into the lower set and the top tubes come down to the exhaust tips. The guy I took it to used all stainless and bumped the primary outlets off the SSI's up to 2.5 to match the flowmasters. From then on its a straight shot with no restrictions. He may need to make a custom hanger to support the muffler at the middle. Overall, a great setup.

Man, really... I think Jack Olsen said that a Flowmaster was a little more subdued... Maybe I should try the gutted stock first.

Anyway, thanks for the tip Ben. Someone just got a screamin deal on one of your 2in 2outs on evilBay. $200 I think with the shipping.

I am removing mine this week, as I cannot drive for more than 20 min. without getting a headache. It sounds great for a few, and now I bring along the ear plugs. I work with power tools BTW, so I am not a wuss when it comes to noise. I managed to ignore it for a long time, and then I started driving around it. Not too bad on the highway, but that was the only time .

PO said it was really flowing too well for optimum. Mine is a 2 in 2 out. Let me know if you want it. Cheap.

Daniel,

Is it a flowmaster 80 that you have? Got a pic of it?

[rennch]

V8-Ranch...I think one of the advantages of the flowmaster (or any of them, really) over stock is that you lose significant weight in the rear polar moment, where it really makes a difference.

[SCWDP911]

At the risk of being slammed, anyone have any reasons not to run a glass pack or something like it. My thought is to put it ( a short one like a Thrush) in place of the premuff/cat and muffler. On the outlet side, run a pipe over and to the middle of valance with the dual outlet pipes. Should weigh a LOT less than the two stock items combined. It seems I saw someone post a vid clip here with a somewhat similar arrangement. Just kicking the idea around for now...

I had them on my 2.7, I liked the sound, but they were loud. It was just stuff I had laying around so I tried it.

The triad is bascially a series of glass packs so that is done all the time.

as to the flowmaster being lighter than stock I would kindly disagree. they are really heavy.

Remember this before I started my business I used flowmasters but they were just to loud, to hot(they radiat allot of heat) and to heavy.. thus my soulution. I do however love the sound so I tried to make our muffler sound as close as possible but toned down. which I think I pulled off pretty well.

If you want sound try stock with a second tail pipe. going to an aftermarket muffler is just to expensive.
V8 ranch if you would have put in a hi flow cat to your previous setup you would have been happiest the by pass makes them real loud good luck guys

[89911]

Use the Magnaflows. Lighter and sound great. No issues after 2 years.

[Oh Haha]

Look at Flo-Pro mufflers. I have one for a late model Camaro, single in/dual out with one side capped. It sounds great and really isn't that loud unless you are getting into it. I can carry on a conversation at speed without any problem. Cheaper than FM, too!

[Oh Haha]

On the car.

Ben, do you mean the high flow cat with the stock muffler?

EDIT: I trid uploading a couple of videos of my car to YouTUbe but had no luck.(First time trying.)

I can send them if somebody wants to host.

[SCWDP911]

Would you send them to me, I cannot host, but would really like to hear it.

@ 89911: Which magnaflow are you using?

@ oh Haha: Do you have any pics of the install? (Underneath) And which flo-pro are YOU using.

I guess the only reason I was using the Flowmaster is that it was a known commodity. And, since it's primary an autocross/race car, I wasn't SUPER concerned with the noise. If I had my druthers I'd run straight headers.

[Oh Haha]

Sorry, no good pics from underneath but if you duplicate Jack Olsen's setup that will work. Mine is a single in, BTW. Simple pipe from the premuff to the inlet and then one pipe for the outlet coming into the stock location. The other outlet is capped. I tried using it as a dual out and found the resonance to be too much. I don;t recall the part number of the muffler but they do carry generic sizes for dual inlet systems.
I had the muffler guy weld a tab on the backside of it so I could use the stock hanger. I had to connect two HD hose clamps together to simulate the muffler straps as the stock one wouldn't work. I bought the Flo-Pro because it was cheaper by almost half of the Flowmaster. Now, I see a lot of the street rods and pro street guys around here are using them.
