Why is my WS2 raspy?

[AccordWarrior]

Hi all,

This has been bugging me for awhile, but I figured I'd post it up and see if anyone has a similar story.

So about a year ago I had installed a Megan header and a Carsound Cat in addition to the World Sport 2 catback I already had on the car.

I noticed immediately it didn't sound right, but that was due to a flexpipe leak. I had that leak fixed, but I still noticed that it would produce a rasp in the first 2 gears at about 50% throttle. I was showing my friends the problem, and they said it sounded like the muffler was to blame as the rasp was definitely coming from the back of the exhaust.

Now, I had the catback off it's hangers when I put on the header, but I did not take it apart at the axleback section.

Is there any explanation for this newfound rasp? There was none before the header/cat. I had the flex replaced and the rest of the exhaust checked for leaks.

I'm thinking either there's still a leak at the cat I'm not hearing...or the axleback section has a leak caused from taking the exhaust off that I'm not seeing, or the innards of the muffler broke?

I've been under the car and I don't hear any leaks at idle. There's no noticeable cracks or issues with the seam between the pipe and the muffler. There's also nothing noticeable at the flange...but I dunno.

Almost every reason for raspiness increasing is because of the cat. I guarantee you that if you put the stock cat back on, it will sound great. The raspiness would have been a lot worse if you put a test pipe on there

i would have to agree with the above based on on previous experience.

I think drloveskudang put a carsound on his car and he said it got a bit raspier a while back when he had the car.

x2, i noticed that when i put my carsound cat on, its worse when it is cold...

[owequitit]

I also agree. I had a tiny bit of rasp on the F22 when I put the header on, but it got a lot worse with the carsound cat.

Now here is something interesting.

I was talking to Cisco about his Catco, and he said it sounds great.

So it may just be the cat itself, but not cats in general.

I don't typically hear of complaints about sound with Random Technologies either.

I have never been a real fan of Magnaflow mufflers either, so it is possible, it is just how they tune their stuff.

I had a carsound on my previous accord with a megan header and an obx exhaust and never had any raspiness. All my piping was I think 2.25"

woah, after reading this i think i'll stick with a OE like cat.

[starchland]

this is wierd.

my setups

maganflow cat megan header oem catback -no rasp

magnaflow cat megan magnaflow catback -farty

magnaflow cat magnaflow catback rsr- no rasp or fart

its the cat

[starchland]

but lets also define the term 'rasp' please and differentiate between farty.

but lets also define the term 'rasp' please and differentiate between farty.

rasp means like a little ricey, and very annoying at some times.

right now im running a dc sports header and dp, test pipe, custom resonator and catback, and a magnaflow muffler. and to tell you the truth, i hate it. its so damm loud. can i run a turbo on my stock cat???????


your CAT is a piece of junk. period. if you bought a cheap cat, it wont delete the sound good. get a good one. like a vibrant or the ones off ebay.

[rickyduckworth]

you can always use a longer resonator to get rid of the raspiness. i had to use an 18" resonator on a boosted saturn i used to have. even with the turbo acting as a muffler, it resonated at a certain rpm and was TWANGY!!!!!!

a resonator's effectiveness is determined by it's length.

ask jboyce, he's had his penis in another dude's mouth, he'd know

i have a 25" long resonator and it dosent do shit.

yeah it does, take it off and see if it gets louder.

and a resonator is NOT a damn glasspack turned backwards, that's what a lot of places sell as resonators. resonators are perforated core and LOOK like a glasspack on the outside, but inside are nothing alike.

even with a magnaflow muffer and no cat, a REAL 25" resonator should keep it pretty smooth. me thinks you got fucked

[foamypirate]

Ricky is right. I'm running an 22" resonator in my exhaust (Custom magnaflow catback), and I only ever get rasp when I rev it up in neutral and let it drop down...
