Flowmaster 80 Series
Posted: Sun Jan 20, 2013 9:54 pm
Like the title says, I am thinking of putting a used 80 Series Flowmaster on my '90 Yellow Indy, for the time being. I am posting this up here because the
"Exhaust" threads look pretty dead (what, three new postings in the last year?), and because it hasn't been done on my car yet, so I don't want to drop the speculation onto the car's thread in the"Rides" section yet.
Basically, the muffler was hanging off the back end of a 3rd-gen 2.8 V-6 Camaro at the junkyard -which would have made me laugh if it wasn't so sad that someone threw the car away. It was a half-price day, and the muffler looked in really good shape (dirty, but undamaged), so I popped it into my stash for $5-$10 with the decent stainless slash-cut tips still attached. I didn't have a particular need for a transverse-style "Cross-Flow" 80-Series, but it was too good to pass up.
The Yellow Indy I have came with a Cherry-Bomb glass-pack on it, with an otherwise stock engine and exhaust system. At first, the car sounded pretty good, and it still sounds okay to me (especially once warmed) so far as the quality of the sound, but after driving the car around a bit I find that it is a bit too loud and droning for my tastes with the glass-pack it came with (it is my new daily driver until I get some work done to my 3800 SC GTU, which is also too loud despite having five mufflers tucked in underneath it). So, I started thinking about this Flowmaster...
To make it fit right, I would have to cut off both of the tail-pipes (each one is ~2.5 feet long, with the tips, maybe three feet) after the 90-degree elbows that attach them to the muffler (one of them is punctured in the 90), and turn the muffler over to put the inlet on the left instead of the right. Then, I would have to attach a fresh 90 onto the inlet, cut the tail-pipes to the right length, and reweld. After that, it is just a matter of attaching the right hangers, and I am done. The hangers cost a few bucks each, and I can buy the 90s for cheap enough at Autozone, but I would rather avoid crinkle-bends, even for a temporary exhaust system -it might be on the car for a couple of years before I get a chance to upgrade the engine/tranny/exhaust to what I really want on the car, and I would be embarrassed to have crinkle-bent piping on the car for that long. Unfortunately, U-bends are alot more expensive now, and I won't waste any of my old 2.5" stuff on what I consider to be temporary in any scale anymore -that stuff is too expensive to replace now. So, for $17, I can get decent 2" piping to finish the job right, but I'll have to wait for it. I would also have to buy a reducer to allow the tiny factory Beretta exhaust-piping to fit the Flowmaster's 2.5" inlet. With all the piping and stuff, I could just buy a cheap off-the-shelf muffler, save a lot of time cutting and welding, and be sure that the car will be quiet enough for me, until I get to do my upgrades (and then quiet won't be one of my goals anyway ).
My '89 Camaro RS Police Special 350 has one of these 80-Series under it (I think it might be the 3-inch model, though), and it sounds very good with the car's Headman headers, but it is a V-8 -my 'old' '88 Camaro has an open exhaust with a shelled-out cat behind a modified GMC CFI 350, and that makes the RS sound like a Prius (also pounds the RS for acceleration, too).
Anyone here have experience with an 80 Series Flowmaster on a V-6? Any other Flowmasters on a V-6?
