Easier, cheaper, more freely flowing but not as quiet. Flowtech afterburner 50363FLT 3in 2.5 out
Your setup does look good and I'm sure it sounds great
That's exactly what I fabricated(3" In dual 2.5" out) but added two sets of Heddman Hot tips resonators where the old trumpets sat. Looks good with the four pipes coming out the bottom and its a bit easier on the ears. Those Flotechs fit perfect and flow well but they do roar.

The '88 formula I bought has a Spyntech on it. I don't mind the way it sounds from outside the car but inside it just drones. Don't like THAT at all. So I've ordered this Magnaflow to put on it.
The Magnaflow is probably a very good muffler, but I don't see how some guys claim to mount this 18" long muffler with it's attached pipe without cutting the trunk , modifying the cradle or hanging it below the cradle bottom. IIRC Bmwguru came up with a trunk modification to use it and I can understand that. Others have cut the trunk and I can understand that too, that is ,if the trunk is unimportant to you. Until someone proves otherwise I will continue to believe that one of the three mods mentioned is necessary to install this muffler in a Fiero. While I am not crazy about the Flotech Afterburner 3" in 2.5" out crossflow and the sound that I have, it does fit perfectly. The Afterburner is 14" L while the original Fiero muffler is only about a foot long and the Magnaflow like the Flowmaster is 18" L. That's big for the space that the Fiero dedicates for a muffler.

That is hands down the best sounding 3800 I've ever heard. Just that exhaust change is enough to make me reconsider a 3800 as a potential swap. I've always liked the engine, but can't stand the exhaust note on most I've heard.
Dave, have you used that modded muffler on a stock 2.8? I'd be interested to see how it sounds.
I'm hoping someone at Magnaflow sees this and sends me a free muffler for this post
Magnaflow 14277 examples that I have built.
Volkswagen VR6 Fiero
3800s/c. series III. 3.4" pulley, Northstar TB, 1.9 rocker arms, unequal length headers and muffler inlet mod with added baffle.
Here is a later video of that same car with short stack intercooler and 3.25" pulley drop added..
Magnaflow 14267 examples that I have built
Series III, 3.0" pulley, 77mm Northstar TB, XP hot cam, ZZPstage III ported heads, unequal length headers, methanol injection. Currently 2.8" pulley: no video yet.
Series II, 3.25" pulley, Northstar TB, 1.84 rocker arms, unequal length headers. Currently added 105lb valve springs, 3.0" pulley and methanol injection.
There are a few more that I have built using those two mufflers. Sabooo's uses the 14267. Michael's turbo 3800 uses the 14277. Typically, I will use one or the other depending on customer preference. It is one of the few stainless steel mufflers made that fit nicely. I've run others and some sound just horrible. Keep in mind that the supporting mods will drastically change your exhaust note as well.
OK its 14" L but I still don't see how this muffler can be mounted without trunk mods or without having it hang below the cradle. My Flotech Afterburner just clears the bottom edge of the cradle. Look at alex4mulas next to last picture and you can clearly see the crossover pipe below the muffler hanging very low to the ground and below the facia. Go over any incline in the road or hit a speed bump and you'll have problems. Heck I'd love to try this muffler but the fit just doesn't seem like it will work without cradle or trunk mods. Am I wrong about this??
UPDATE: Did more research on the Magnaflow V6 Camaro Crossflow muffler. It may sound nice but its a difficult fit AND I also discovered that it only has a 2" core After finding out about the 2" core I scrapped the idea of trying this muffler. In contrast the afterburner that I use has a full 3" inlet and core. The oulets have a full 2 1/2" core and outlet sizes. Its far less restrictive than the Magnaflow which I believe causes you to lose valuable horsepower but I am sure that it produces a better sound. ------------------ " THE BLACK PARALYZER" -87GT 3800SC Series III engine, custom ZZP /Frozen Boost Intercooler setup, 3.4" Pulley, Powerlog manifold, Northstar TB, LS1 MAF, 3" Flotech Afterburner Exhaust, Autolite 104's, MSD wires, Custom CAI, 4T65eHD w. custom axles, HP Tuners VCM Suite.

Hey I got my muffler in and the guy who is going to help me finish my exhaust was wondering what the bend radious is coming off the muffler going towards the drivers side is.

ok so the two pieces i would need to use to replicate this exhaust. Would i be able to get them easily say at the local auto parts store and/or exhaust shop?
That's exactly what I fabricated(3" In dual 2.5" out) but added two sets of Heddman Hot tips resonators where the old trumpets sat. Looks good with the four pipes coming out the bottom and its a bit easier on the ears. Those Flotechs fit perfect and flow well but they do roar.
Same here. Flowtech muffler with Hooker resonators on my Indy SD4. This pic shows how close the size muffler is to stock.
