I have a Descendant exhaust and it's definitely loud, but now I can't control myself and must get louder. Can anyone chime in on as to how I might go about doing this? I would get headers, but the weapon-r one seems unreliable (CEL lights) and i'm not sure if a CAI is worth the cash. Open to any ideas.

Thanks!

Drive everywhere in first gear. And don't forget to have your windows down with your radio all the way up. It also helps to put all kinds of flashing lights and strobes all over your car.

headers would be the best bet. im sure there are other headers out there that dont throw a cel or if not some should be out soon. i dont have headers but isnt there a way to fix the problem with the cels?

yeah unfortunately there are no others at the moment so i guess i might have to wait on that.

if you really want to get loud.. just take the cat back completely off and leave it that way lol. ridiculous!! but as far as the weapon r header. you can get the cel eliminator just you have to figure out which way to turn it so the light dont come on (which i have yet to do)

has it been discussed on the forums? i'd love to be able to do this.

has anyone taken the resonator out of a descendant exhaust?

holy rasp. think i'm gonna look for other alternatives. i wonder if anyone has test pipes.. :ponder:

Are you saying you think test pipes would not be raspy?...

more like asking.. i'm just interested in making it louder without sacrificing the deep sound. i don't want any rasp at all.

Pretty much any exhaust modification that eliminates a cat or resonator will give you rasp.

I stole this idea from 2tcornot2tc, but you can remove the bolts in the last section of the Descendant, just before the muffler, and throw some washers in there. This will leave a gap creating an "exhaust leak" which will make it a bit louder. Worth a shot if all you are going for is volume and you shouldn't even need to jack the car up.

I'd like to hear that! You probably wouldn't even need more than one washer.

And you can keep adding more washers untill you get the ear piercing sound you're looking for. Plus, washers are WAY cheaper than test pipes and or a header. The downside is you will have crazy hot exhaust gasses coming out pretty much under the rear seat, so you don't want to sit at idle much, if ever....

Can you say co2 poisening! ;{

I'm sorry, but this washer idea sounds REALLY dumb. The exhaust gasses are meant to be exiting from the rear of the car for safety reasons- namely so that you don't breathe them yourself.

Hey, I never said it was a GOOD idea.....just an idea....and it WILL make it louder....but redlights and stop signs will be your worst nightmare.

Or intelligent people that will see your exhaust leak when its cold outside and laugh at you

definitely interesting. gonna give it a try. how dangerous are the gases? is it gonna smell bad inside the car?

Carbon monoxide can kill someone in a good size garage in about 5 or 6 mins, so id say their pretty bad lol. idk my opinion i would just get the trd axle back and go for a tone over stupid loud. unfortunately you cant make a 4banger loud without having it sound like butt hole... shoulda got a v8

-but do what you want to do since its your car and the only thing that really matters is if you like it not what anyone else thinks. post a video of what it sounds like if you decide to go this route

hahaha i love how everyone uses wikipedia to prove a point even though it could have been anyone writing the post. i do believe it though since were talking about a space that will have a constant airflow... while driving a least ha I guess this just means he should only spend 4 to 5 hrs driving at a time if this "mod" is done

if this "mod" is done..especially on a large scale..i can full expect a news report on "CO2 Poisoning threatening the lives of Toyota Scion tC owners"

I'm not sure I follow. He asked if the gases were dangerous and I posted information showing that they are indeed dangerous.

And for the wiki haters here are 2 from Government websites.

I don’t think it will smell bad, I looked today; the area of the Descendant exhaust where you would do this is very near the rear, under the cargo hatch, and about 10-12 inches rear of the rear seats.
I currently live in a state that has NO vehicle inspection what so ever. If people can ride around in V8 trucks with no pipes, and old Buicks with true exhaust leaks day after day, and be fine, (I see it daily) I seriously doubt there will be any negative effects. Co2 is what hurts you, and is basically caused when the engine does not burn all the gas in the camber. Which engine do you think burns cleaner and more efficient: a 1999 ford V8 truck with 100k+ miles, or a 2011+ Scion tC with less than 50k on it?
I’m still not saying it’s a great idea, what I am saying is, it is not as bad as some people are insinuating.

VVTinme, please keep the personal attacks to the yoursciontc forum where people just argue and fight; this is the Scionlife tC2 area, where we help each other and not belittle people for ideas they have.

I'm sorry if I've committed the cardinal sin of trying to get someone to realize the stupidity of his idea.

Well, the "washer" idea is a bad one. If you want loud and deep. Get the weapon R header and then add a large resonator on the exhaust. It should still be loud and deep... And you don't have to worry about safety of yourself or our planet.

Durp, I could be wrong on this, but I am 99% sure the header removes the catalytic convert, which is what "cleans" the exhaust gases. So if you are worried about the planet, that is NOT the way to go. The washers would be installed at the rear of the cat and resignator and wont remove any emissions equipment. Safety is the only concern.

exhaust leaks??? really??? you need 3 things for this it make a huge difference...1 sawzall, 2 welder with stainless steel wire instead of copper im asuming your exhaust is stainless, 3 depending how long your resonator is a 1 to 2 foot piece of 2.25in exhaust tubing...take off piece of exhaust with resonator (midpipe), cut the resonator out at both ends, slide 2.25 piece of exhaust tube in resonator and weld at both ends, finally weld midpipe back together and reinstall.

@Druidiron, you are correct but I was mainly providing a solution. I was basically stating that it would be a better alternative to an open exhaust leak. Haha I am in no way a tree hugger either. Just to get rid of any assumptions.
It was a simple joke sir.
