Killing rasp

[dantheman68]

okay, now I got my hands on an equal length catless pipe, knowing exactly what bag o' worms i was opening up. So before i get flamed out of the forum, for those of you guys that have catless setups, what is the best way to **** the rasp?... I only have it at about 3.5k-5K rpm, but it is terrible, I was thinking of adding a *better* resonator in the spot of the stock one, but think this will do little to quiet it.

These are the options I thought of.

1. add a glasspack in place of the resonator.
2. add a chambered muffler... uh somewhere under the car (might be a challenge)
3. add a high flow cat in place of the stock resonator (seems to defeat the purpose of the catless pipe to me... but i digress
4. add a "better" resonator in place of the stocker

P.S. the rest of the exhust is completely stock, down all the way to Ford mufllers, and piping... its lasted quite long (8 years according to my records)


Opinions on this topic are welcome.

Thanks!

option 5

sell me y pipe, go back to stock, no rasp

gee, thanks for the help


perhaps I should have made it more clear, but I know I probably will never be completely rid of it, but what forms of success have you guys had... and what methods?

Add a large Magnaflow resonator. Stay away from dynomax and flowmaster mufflers. I prefer Magnaflows and Borlas. My car does not have any rasp.

A resonator "is" a glasspack.

Put in the biggest one you can find, or put in two or more to totally fill the space.

You can then run whatever mufflers you want.

Works the same whether it's a catted or catless Y-pipe.

I had $10 glasspacks on one of my Gen 2s, but it had a big, fat resonator. IMHO it was the best-sounding V6 I've ever heard.

A friend of mine ran a flowmaster hushpower muffler as a resonator on his v6 alfa.
Sounds sweet no rasp great tone.
