HI GUYS SOMEBODY CAN TELL ME HOW CAN I ELIMINATE THE RASPY SOUND ON MY TC.... I HAVE MY HEADERS DONE A 2'1/4'' PIPE AND GREDDY EXHAUST... BUT MY TC STILL WITH A RASPY SOME TIME IF YOU HAVE A SOLUTION, INFORMATION OR TRICK PLEASE LET ME KNOW...

THANK YOU ALL...

hey.. i had some rasp when i just put on my headers, but this is how i went about it.

when i put the headers on.. i had the megan racing s-pipe to a strait pipe leading to a magnaflow muffler.. so i didnt have any resonators or cats.

so you can only imagine how it sounded haha.

then i put a resonator on.. it quieted it down a little.. however i was gettin rasp between 2500 and 3000k rpm.. so i decided to add a magnaflow hi-flo cat.. and that killed ALL rasp.

here is a video i made today of my exhaust.. cant hear it that well, but you can tell their is no rasp.. the current set up is:

Megan Racing V2 Header > Megan Racing S-pipe > Magnaflow Hi-Flo Cat > Magnaflow 30" Resonator > 2.25" mandrel bent midpipe > 2.5" custom mandrel bent axle back w/ magnaflow muffler.




basically the way to quiet the rasp is a resonator.. the way to get rid of it is a cat imho

^ The consequences of not reading up in Scionlife before adding a header.... The above solution is a good one...

The cheapest solution I found was the megan racing header with the precision muffler axleback.... little to no rasp without need for resonator or cat install...

Running a GReddy/HKS/Etc... will all have some nasty rasp with a header install... unless you follow the advice above.

ya.. any "japanese" brand will have some rasp for some reason. i have a magnaflow so it sounds deep.

but thanks wds for agreeing with my solutions

this is a bit off your topic but i was thinking about putting a header on mine, did you guys have any problems with your car running richer after the install? check engine light?

Neothin

a header will either come with or you'll have to purchase separately an antifouler which will eliminate the CEL caused by a header installation

ya i have the DC Sport header with HKS Hi-power exhaust and some scionfx intake but holy crap RASP....im thinkin resinator.....

now when people refer to "rasps" is that the kinda sound from a ricey honda exhaust? kinda like a lawnmower?

i have the megan v2 headers and i'm thinking about getting the megan exhaust but keeping the stock spipe and midpipe. imma assume major rasp-ness?

tC9o9

well if your gettin the OE-RS exhaust i wouldnt expect much rasp.

and rasp is.. a hard noise to describe.

just get a resonator put in at your local muffler shop. got a 37" resonator and no rasp at all.

Sort of.... even worse though....

It's a horrible sound, no matter what your preference is on exhaust sounds... people cringe... some resonators help, not all do... so going with the high flow cat as well might do the trick.

Wowww Premier this is a nice description of the "rasp" you are good dude.

tc2nut4

don't you people EVER search??? I mean do you even attempt it?? Does the though just vaguely fire in one of your neurons or does it seriously not even occur to you????

This needs to stop. I have a DC Sport header and a magnaflow exhasut and it was really raspy. I put on a Magnaflow resonator and everything was ok.

So the answer to your question is.......Put on a resoantor!
