FAQ: Mufflers?

What mufflers have you all used that are good. I think i want to replace the oem mufflers with something else. I would kind of like to not spend a ton of money on it so unless i somehow find it on ebay or something for cheap, flowmasters are out of the question (unless im convinced they are worlds better than anything) ive heard borla are good and they seem to be reasonably low priced. glasspacks would be an inexpensive option for me. Tell me what you think. (in case it matters, i have a 97 s/c with all stock exhaust)

flowmasters suck. I am partial to dynomax ultraflow and its cheaper
copy, the hooker maximum flow. They are essentially the same, but the
max flow is cheaper because its aluminized steel, not stainless. They
have the best flow capabilities, are quiet at idle but scream at WOT.
The both have a straight through design. You will most likely need a
resonator to eliminate drone.

Hooker Aerochambers flow very well too and will be a little bit quieter than the max flow.



The mufflers that flow the LEAST are flowmasters and thrush turbos.

I haven't replaced my mufflers yet, but based on reports from other L67 cars, I'm probably going with Borla Turbo.

Anyone make a recording of the Hooker Aerochambers? I heard they sound really good, but I don't want anything loud.

JUST dont put on mufflers like me !!!!!

i loved both setups i had and both used magnaflows

A JEGS sales rep told me magnaflow turbo and borla turbo sound alike, borla costs a little more.

any sound clips of either of them?

I have some extra cash, and I wanna get some stuff. I already decided that I need new plugs, and to seafoam my engine. But I also wanna pick up two mufflers, and I don't wanna drop that much and get something I wasn't looking for.. so if anyone can drop some tips on an exhaust and tip brand, that'd be pretty rad. I was looking on jegs and I came across this



29.99 each but I was gonna go with dual outlet
3.00'' Center Inlet/ Dual 2.50'' Outlets9.5'' x 4.0'' x 13.0'' body
19'' long overall

has anyone heard anything about these?

If you wait until tomorrow night (hopefully) I can let you know how some inexpensive glasspacks are

alright good deal. will you lose low end torque using those?

not with them that far down the exhaust line, the difference in back pressure at the heads should be acute. Plus, our engines aren't that bad with low back pressure in the first place thanks to the s/c and general design of the motor (as opposed to opening up a dohc 4 banger too much)

well dang, throw those beasts on man.

Lost torque? Get a smaller SC pulley. Beautiful, isn't it?

I'm going with Borla when I get to that point. Heard they sound good.

expensiveeeeeeeeeeeeeeeee

The JEGS guy said Magnaflow sounded much like the Borla at a lower price. The Borlas were $100 each I think?

You gotta spend a little to get stainless at least.

cheapest borla muffler is 114

From videos and such of other people's magnaflow mufflers, I've found i'm not particularly fond of them for some reason. Flowmasters are hit or miss. those bastiches with V8's can put anything on there and it sounds good hisssss! I'm doin glasspacks cause I haven't really seen it done and I want to try something different. Plus they should be a pretty easy install. knock on wood

I'm pretty much as cheap as they get, but don't use a thrush muffler. They have a lot of back pressure.

I would recommend hooker maximum flows. They are a copy of the dynomax ultra flos, but are much cheaper because they are aluminized steel (obviously the ultraflos are awesome but they will cost you). Hooker aerochambers flow extremely well too and have a nice tone.

If you MUST go cheap (very cheap) I would go with the summit turbos before the thrush mufflers. They flow surprinsingly well for the price.

I had a feeling that they wouldn't be too great for the price,

# Max Flow MufflersInlet: 3"
# Outlet: 3"
# Dimensions: 4-3/4"H x 10-1/4"W x 22"L

not bad for 69.99 at least I can expect quality for more cash

If you go with a single, long, 3" diameter muffler, expect it to be loud.

what would you reccomend? i want it to be sound good, but not like retardedly loud

I would scope out ebay for a while and try to get a 3" resonator or circular 3"muffler and follow with 2x 2.5" or 2.25" mufflers after the split.

If you don't mind not having two tailpipes, a 3" resonator with a single good quality (not a summit turbo or thrush) 2.5" muffler will do nicely and save a little weight.

I am running dual Borla XS/Turbo mufflers. Im a cheap ass 6@$†@®d, but after I heard them on a few Big Dog Regals, I was sold. When you are cruising around town stopping for stop signs and putzing about, the car is really quiet. When you get into it, it roars with out being harsh. At idle it sounds stock unless you are next to the tip. I got mine on Ebay at a good discount. I just checked and they run about 100 each shipped on ebay, but if you are patient you can probibly find a slightly better deal.

At the same time, Borlas are just fancy glass packs. Who knows, there has to be a bargain muff out there that sounds similar.

As for tips, I am pretty happy with Ractive tips. I know a lot of other rivy folks are running ractives. The chrome is still in great shape on mine. These are what I am running:

Drop a part number in froogle.com and some decent deals should turn up.

is there a noticable differerence between round and oval mufflers? or is it just for looks? these don't look too bad, and for the price, it's tempting. thoughts?
