I took the liberty to cut 4" out of a flowmaster muffler today. Just wondering if anyone has done this before and if so how does this sound like... I may use this, if not it will be for sale..

I have personally installed 3 different Flowmaster 80 series mufflers (F Body Style) in to 3 different Fieros, two 4 cyl's and one V6 with no fitment issues.

Why cut one up?

well, i placed one up in the fiero once and noticed that it was a little to long. I figured it would be difficult to get the angeled piping to curve coming out of the muffler and then to the tips. I thought if the stock muffler is 12" in length why not shorten the flowmwster muffler to 12" in length? By doing so I'll be able to get better exhaust flow with mandrel 2.5" tubing... I was able to cut one today, I took some pic's of the before I welded, but once it was finished the battery died in my camera. I'll have some pic's tomorrow when i go into work.

this first pic. is the muffler cut into three..



this second pic. is a view of the inside.



this third one is with the outer in place



the last two pic's is the final product, you can see by the last pic. the 4" piece removed.




I should have the picture tomorrow of the two parts welded together. Sorry my camera ram out of batter power.

They do come in different lengths but most of the shorter ones are single in on one side and the two out lets are on the other side making the tail pipes a pain to make. Dan

I never thought of doing that. Good idea. I wonder what the sound "difference will be"?? Keep us posted on how that thing sounds.

I just removed the bottom portion of my trunk in my replica to use the OEM size F-body 80 series. (just to give it a bit more room.)

If I recall, I thought I saw it in one of Loydes build threads, but I could be wrong.

This photo illustrates how my Flow Master was modified to be package in basically stock position, without any changes to the trunk sheet metal. Also there is enough room between muffler and wall of trunk to place a thin flat 1/4 in stepped stainless steel "pocket", to hold a 16 in x 8 x 1/4 in thick heat shield material (fiber with one side alum face). You just screw the metal narrow pocket to the trunk wall and drop the pad inside from the top. This was done on my 88 GT, fits nicely between crade and trunk. The inlet was modified to 3 in. and the 2 1/2 in. outlets were fabricated to exit to stock trumpets location. The mandrel bends on both sides have a good even radius, believe it is a series 80, but not positive.

I have a flow master 80 on my gt. The only thing we modified was the inlets and outlets we cut them back for a better curve going out to the tips. It sits up in the stock position without a problem. Its not even visible unless you stick you head under the car. It sounds really deep and not very 2.8 like at all. I've had at least 2 people yell light it up at me when going through a parking lot.
