The Megan muffler, is this a noisy muffler? Or a smooth one, which makes nice sound instead of a lot of bad noise?

Resonators are there to... well exactly what they say - resonate. A resonated system will always sound more smooth and mellow to an identical non-resonated setup. If you're looking for rasp then a non-resonated system is the way to go. I had a non-resonated setup on my wrx and it sounded like a racecar. Swapped out for a resonated setup and it sounds much smoother now.

IIRC the stock exhaust on an ST is 2.25". If you want to increase that, 2.5" is the best way to go from what I understand.

Stock exhaust piping is 1.75". For ST's I would suggest 2.25" upgrade - 2.5" if you're going to end up Forced Induction.

For GT's I would suggest just getting 2.5".


Make sure on any setup you put in at least an 18" resonator.

I've had an SP2 style muffler, N1 style, and EVO2 style, and the best I've had personally, and heard on other Celicas is the EVO2 style muffler. If you want a nice deep tone PLEASE look into an EVO2 style.

Specifically, this is the muffler I had on my Celica - 2.25" piping. Best sound hands down. Clicky

The resonator is separate from the cat, and is somewhere before the muffler. It is NOT needed to pass emissions (I don't even think it affects it, just sound), but you will need a cat to do so.

its small. IIRC its just under 2.5", and has compression spots where it goes over the crossmember.

a couple of pics of a custom b-pipe i made for dustins swap.

3" mandrel bent stainless, with the super cool exhaust cutout. (remote actuator not pictured)

What's the largest diameter exhaust you can run over the rear axle?

i've seen as large as 3" over the axle, but it takes a VERY good fabricator to make it work properly. (im not nearly that good yet....lol)

IMO anything larger than 2.5" shouldnt run over the axle, going that large,(3" or bigger..lol) with the bends it requires, IMO negates the advantages of having the larger pipe.

a couple pics of a downpipe and b-pipe i made for steffs turbo setup this weekend, to mount up to the greddy cat-back she got.(you can see where i added the v-band to the existing pipe laying behind the exhaust in the first pic.)

2.5" stainless mandrel bent, with custom turbo exhaust housing flange by randy (97lestyousay) and some super sweet vibrant v-band clamps. with those vbands, you get perfect alignment of the exhaust because the flanges have a male and female side to align them, and you also do not have to totally take them apart because of the cool snap together v-band that holds them together. ill get a couple pics of one that was left over later.

That pulled up pretty nice, the first pics I saw with the flange sitting on the turbo made the gap
look a little bigger. smile.gif

Here is a clear explanation of each a resonator and catalytic converter as well as their function. (courtesy of carexhaust.com)

Catalytic Converter
As already mentioned, the catalytic converter reduces harmful emissions from engine exhaust. It uses a combination of heat and metals that act as catalysts. A catalyst is a metal (or chemical) that causes other chemicals to go through a reaction without being affected itself. The inside of the catalytic converter consists of metals like aluminum oxide, platinum palladium. These metals cause the carbon monoxide and hydrocarbons to react and produce water vapor and carbon dioxide which are much less harmful to the atmosphere.

Resonator
The muffler alone cannot always quiet all of the engine noise. Many car exhaust systems also include a resonator which is like a mini muffler. They are usually straight pipes filled with sound muffling materials. The resonator can be either before of after the muffler in the exhaust system.
