muffler upgrade

[tercelwill]

I love my terc but i'm getting a little bored with the sound. I'd like a deeper throaty note with mild to moderate volume like a muscle car. I defiantly don't want an obnoxious ricer buzz. Does anyone have a suggestion for an aftermarket muffler? or is the 3-Ac just to small to sound cool? also i'd like a cheap one

This exhaust tip sounded real good on a V6 with no muffler...but run thru the converter. They are straight thru...but have fiberglass in them. Cost is a bit high.

Saw something similar for a lot less a a car parts store...Advance? Best is something with a stainless shell and fiberglass inside if you can find it.

Best sound otherwise is probably a turbo muffler...I tend to use the straight thru glasspacks due to price and fit...but they don't sound all that good.

These are the best sounding mufflers that I have ever heard http://www.spintechmufflers.com/ These are for small engines http://www.spintechmufflers.com/muffler ... at_73.html

I just put a turbo-style muffler on the '83 after building the new engine, it sounds very good, not too loud (no converter now), nice deep note, not obnoxious and annoying for long drives.

Those are pretty pricey mufflers! Unless I find one at a pull-a-part or something, too expensive for me. I put on a cheapo $20 turbo muffler and it works fine for me.

Your best bet for a nearly bolt-on performance muffler, that will give a deep tone, without the farty ricer noise, is probably a Dynomax Super Turbo. Their part #17771 has a 1.75" inlet/outlet, same as the stock 4WDs, and the body of the muffler itself is about the same size too, meaning all you really have to do is either carefully saw/grind the hangers off the stock/current muffler and have them welded onto the Dynomax, or just have new ones made from 1/4" steel rod. Exhaust shops have pre-made L-shaped hangers they can bend around, but you'll have to be nice and ask them to use the muffler that's on there as a reference, since my experience is a lot of exhaust places just put the hangers on the rubber mounts, and weld the other end to the muffler, and pay little to no attention to looks or how well it's handling the weight of the muffler.

If you want a little more flow and are willing to put up with some more noise, Dynomax also makes a slightly smaller muffler, but it has larger diameter tubing. This is part #17777, and it has a 2" inlet and 2 1/4" outlet. The body itself is much smaller, a few inches shorter, and so it's muffling capabilities are reduced. You'll have to expand the stock exhaust piping a bit at the end to fit the 2" tube, or use an adapter (which isn't a problem, and might actually be preferable due to the shorter length), and though you can still use the stock hangers on this one, you might want to use new hangers since you can hang this smaller muffler up a bit and out of the way, due to the tiny body.

Also worth mentioning, Dynomax mufflers have a lifetime warranty. Save your receipt and when the muffler rusts out (as any aluminized steel muffler is sure to do), you can get a new one. I recommend purchasing from Napa auto parts, since they will order you a new one and exhange them on the spot, rather than have to go through Dynomax and mail the old one in to have a replacement sent.


Other performance options are from Magnaflow, which offers three 1.75" stainless straight-through mufflers in various configurations. You do risk the ricer fart-can sound since they are a straight through design, BUT Magnaflows are a quality muffler with stainless steel packing material, and are HEAVY, so they shouldn't be as raspy as a cheap ricer one. These can be expensive, but sometimes exhaust shops that carry Magnaflow will give you a good deal. These also have a lifetime warranty.


The cheapest option is probably a Thrush Turbo, which is basically a Turbo muffler made by the same company as Dynomax (Walker automotive), but without internal flow directors, and no lifetime warranty. These can be had rather inexpensively ($20-30 at Advance Auto), but you can probably only get the larger 2" units at stores. They do make both 1.75" and even 1.5" mufflers, but you'll either have to try and order these at your local Napa/Advance, or go online and pay shipping. For the cost difference, and the warranty, I'd say go with the other choices unless you just wanted a disposable muffler.
