Muffler Options 1988 GT (Page 1/1) pelensky AUG 08, 10:06 AM What muffler brand and part number will fit in place of the factory setup? Mine has a split in it and I prefer to just replace the muffler instead of the rest of the exhaust. The rest is in pretty good shape and I have someone that can weld it in. Steel AUG 08, 11:05 AM Westcoast Fiero has some ready to install options: https://westcoastfiero.com/t/mufflers If I remember correctly on my '88 when I still had the 2.8 engine (it's been a LONG time), I took an 80 Series flowmaster and chopped 4" of length out of it then rewelded the end piece on. At that time they could be had for around $85 from summit. steve308 AUG 08, 02:35 PM Go onto Summits Racing Equipment web site. Look up 'Jones Exhaust". Under the Full Boar (Yes that's the correct spelling) you will find a muffler available that is the same dimension as the original muffler. It's available in a quiet and not so quiet. Just measure the old muffler to get the correct size. fierofool AUG 08, 03:59 PM Flowmaster makes an 80 Series muffler that's the same size and configuration as the Fiero. It was the same muffler used on some of the Camaros. It's a one in, two out pipe configuration, just like the Fiero V6 mufflers. Spadesluck AUG 08, 06:23 PM Welcome to the forum. Another option to help you out would be to use the forum search function to give you an idea of what you need. pelensky DEC 06, 06:51 PM I only found one of the Jones Exhaust Full Boar on summitracing. This one: Jones Exhaust FB2583 - Jones Exhaust Full Boar Flow Deflector Performance Mufflers Click here for more information about Jones Exhaust FB2583 - Jones Exhaust Full Boar Flow Deflector Performance Mufflers Muffler, Full Boar Flow Deflector, 2 1/2 in. Inlet, Dual 2 1/2 in. Outlet, Steel, Aluminized, Each JEX-FB2583 Estimated Ship Date: Today Is this the quiet or loud one? Does anyone know the part number for the other one? OldGuyinaGT DEC 07, 01:41 AM If you consider using the Jones FB2583 check the length for clearance. To ywars ago I was going to build an exhaust using this muffler and bought it on Amazon (still listed there for $41.50 free shipping). When it arrived I found out that the dimensions listed on Amazon are STILL incorrect (the dimensions on Summit I think are right). The problem was that the real length made it too long to fit with 90 degree elbows to route to the tips (I wasn't using the stock tips but I think those have 2.25" inlets and would have to be adapted anyway). I don't think you can make it fit in the unmodified stock location. For what it's worth, I ended up installing the Ocelot cat-back kit from The Fiero Store. A nice system provided you'd be happy with a 2.25" exhaust. flimbob DEC 08, 08:20 PM Bought one(Full Boar) from Summitt a couple of years ago. Got it out to the car and looked at it. Brought it right back in and got a refund. It was close to 20" long.
