Quick Questions, exhaust related... Options

[CPleasure]

First, I have no idea what kind of resonator to get... I guess there's no real difference in any of them but how they affect the sound, but I'm looking around and I see all these different types of resonators, just dont know which one to pick

Second, round or oval magnaflow high flow cat?

Appreciate the patience in advance, I know I'm probably the 783sjhf928 millionth person to ask these questions

FIRST IF YOU LEAVE IT OFF ITS NOT A HUGE DIFFERENCE IN SOUND

SECOND A magnaflow high flow cat IS NOT A resonator

THIRD IF YOU DONT FIND THE ANSWER HERE JUST GO TO ANY EXHAUST SHOP AND THEY CAN EXPLAIN IT

Pertaining to the 2nd question I had... I know a magnaflow high flow cat isn't a resonator, I was just wondering if there were any differences between a ROUND magnaflow high flow cat or an OVAL one... I'm assuming no huge difference, but if there are any I'd like to know...

Round:

Oval:

Again, thanks in advance

the oval seems to be more of a primary cat than the round one, but as for a res. look into magnaflow or vibrant. and dnt leave this out, if u do a full exhaust it will sound like a honda fart can with out it

The shape of a catalytic converter is irrelevant, except that ovals fit under the car better -- more ground clearance. The question is matching the type of converter (e.g. TWC, TWC with air, etc) and its capacity (engine size).

However, I do have to point out that MagnaFlow offers a universal catalytic converter design with a resonated core; two-in-one function saves space in your exhaust design.

Be aware that almost every piece of aftermarket exhaust equipment you see labelled as a resonator is not a resonator. All these underbody round mufflers are just that, mufflers. MagnaFlow's are a good design, Cherry Bombs are bad, but they are mufflers rather than resonators. The Celica, like almost every car manufactured, comes with a stock resonator. Get under your car and tap it; it will ring like a bell. A muffler, particularly the straight-through mufflers popular for underbody use, absorb sound via insulation. A resonator is an echo chamber, bouncing sound waves off each other to cancel out the noise. Mufflers deal with volume; resonators deal with tone.

X2 on this, and your right about the cats, i was just going off what most primary and secondary cat systems look like.

Would you be able to post up some links to this resonator/cat converter you've mentioned?

while this may be the case on a honduh, that is not the case with the celica, provided your not running a "fart can" muffler.

a resonator will make the car more mellow, and quieter.

I found it via the Car Sound/MagnaFlow website; you're looking for ones in the 94400 range. The 2.25" one is the 94404.
