Here's my setup

DME header>second CAT>AR25 resonator> stock resonator> Basic maganflow muffler from muffler shop.

So I though the AR25 resonator would kill all the rasp that I was having, but I was wrong. After so many posts saying that the Ar25 resonator was the thing to beat the rasp I was convinced. I still have the metallic rasp at the higher RPMs. I am at my wits end. I am not sure what to do. I'm thinking more resonators or maybe even a high flow CAT.

Please for the love of god I need a sure fix for the rasp? I need some serious help, I am running out of money and patience.

 

Delete the red, remove the rasp.

/thread.

 

I know that. But I was looking for a solution that would keep the header.

 

try a different axle back now.. they have a big effect on the sound of the exhaust to. they can even contribute to rasp and make it worse.

 

I'm pretty much damn confident that its the axleback. Even after all that and u still have rasp. Get the tanabe medallion touring, i think one of the most expensive axlebacks. But if u hate rasp ull love this axleback. i fergot how long the stock resonator is plus your AR resonator, but im catless with only 14" resonator. and i have no rasp at all, pretty much sounds stock. I have a MMW header which seems like it has alot less rasp then 4-1's but im pretty sure the tanabe will fix it.

 

HF cat will calm it down alot... since you have a aero res it might even kill the rasp all together.
im running WR header, meagan mid and a concept G and it had ALOT of rasp till i put the HF cat. rasp went down by 80% with the cat. im just too lazy to get the aero put on.

 

You can't. You can try and install as many resonators as you possibly can fit and change out as many axle-backs as you'd like..... but in the end you will still have some rasp. At that point, with all the headache, frustration, and not that much noticeable hp gain; it's not worth it.

That's why I ditched my header LONG back and am much happier with a full cat-back.

 

A turbo kit would solve the problem...

 

So does anyone else out there have a Tanabe Madalion touring exhaust with a header. Don't want to purchace something that ultimately still give me rasp.

 

well all i can say is out of all the axlebacks the medallion touring will lower the db the best.

 

what about the new greddy spectrum elite? it is supposed to be the highflow quiet kind

 

hmm i dint kno they made that exhaust for us tc owners yet. Ive heard almost all the axlebacks exept the new greddy SE. according to the site the style is basically the same as the medallion touring, so i guess it depends on what kind of material or packing they use inside the chamber. the website isnt telling me. So i really have no say on it. looks promising tho. might even be the same shiit as the medallion. I for one fully stand by the medallion. Even met the one of the guys at a show. Very cool guy.

 

my greddy sp2 is ridiculously quiet.. i cant even imagine it being loud.. id say thats a good bet as well..

 

sp2 is coo but do u have an aftermarket header? ive heard a nasty sp2 with a megan header on.

 

When i'm driving it sounds like I can hear my exhaust and then the metallic "rasp" sound. it almost seems like the sounds could be coming from two different sources. Could it be that I have some leaks in my exhaust? Could this be the sound that i am hearing?

 

i got that sound with oem exhaust, my resonator is still on back order so my tc sits and waits and waits

 

what resonator are you looking to get?

 

aero ar25, they said by sept 21, but then again they said alot. i've got c.a.i, header, downpipe and straight mid pipes. got rid of my exhaust, trying to fly under the radar

 

get a quality header. and a magnaflow resonator

 

lmao
