exhaust carbon

[phat_levin]

couldnt find this in the search, how long does it take to carbon up the inside of a new exhaust? ive just got a new one and the guy said once it got carboned up it will quieten down a bit....
its a 20v silvertop and it sounds a tad tinny up the front somewhere when you're inside the car so im thinking/hoping that a bit of carbon might fix it?....

..sounds BS to me. See how it is in a week. If it still rattles then go back and ask him why he fed you that crap to cover his ass.

hard luck bro.

yeah mate, you've been had. Just chuck a reso in there, it'll quieten it down and improve the sound.

[phat_levin]

he did tell me that before he put it on, he was recommended to me by a guy from mag and turbo who had his dun by the same guy......maybe somethings loose......
idles reeeeeeaaaal nice tho, gets a tad tinny sounding at about 3k rpm and at certain revs it kind of whistles. i will get someone to drive it so i can hear it from outside the car.
oh, also from the inside it sounds quite tinny wen its cold but that goes away after a while.......
fun and games ay

not a chance, what 20V dosent sound tinny, reguardless of exhaust?

As a brand new exhaust carbons up it does get quieter (or change tone) however it is only a small difference, you will hear a diff but like i say it is only a very small amount. It shouldnot take too long ie a week or two before it is covered in carbon given how rich a 20v runs

may mate was told the same thing, but i told him its a 20v, its always going to sound like that.

In saying that, another mate had a action dan system and ran 2 extra resonators in it, sounded really nice for a 20v.

mine

2 and a quarter, through 2 18" resinators, NON coby, to an rps muffler / tip etc.

nice and deep, and when vvt comes on, it rises a note, not like vtec, that absoutly high pitch noise, just a bit more of a twang, nice noise i think .

nice and deep.

Yes brand new mufflers do change there note and quiten down after a bit of time as they carbon up.

As for how long, it does take a while, possibly a month.
