Last May I got a 40 series flowmaster put on my 1995 3.4. It has a deep sound at lower RPMs but when I get between 3-4k RPMs it has a "rice" sound. Is there anything I can do to stop it from having that annoying sound? Will a high flow cat do it? if so, do I need 2 cats since my car has 2 on it now. Also, I only changed the muffler, not the pipes. Could changing the pipes help also? Thanks in advance.

No, a highflow cat actually makes it somewhat worse. From what I've gathered, Flowmaster American Thunder gets rid of a lot of the raspy sound on the 3.8, so it might work for the 3.4. I've also heard of people putting resonators in place of the cat which gets rid of the ricey sound.<a href=\"http://pics.projectpredator.com/thumbnails.php?album=16\" target=\"_blank\">2003 Zinc Yellow Mustang GT</a> 1 of 701<br />ET : TBD<br />But our shenanigans are cheeky and fun!

or you could add two more cylinders. That should help get rid of the ricey sound. :D1996 Camaro RS Bright Red<br />3.8L V6 A4 3.42\'s<br />K&N Filtercharger<br />Flowmaster 80 Series Muffler<br />Y87 Performance PackageComment

My dynomax bullet muffler acts as a resonator...plus the 3.8 Flowmaster catback has a resonator on the I pipe, so I have 2 resonators and no cat.

Supposedly flowmaster is making a kit now specifically for the 3.4, and it's supposed to sound nice and deep all the way throught the RPM range. Look into that...Comment

Fierdon- Are you sure you have two cats? I thought 2cats=true dual exhaust.

No, some firebirds have two cats. Oe right after another. Also, where can I find a resonator for my car online?1995 3.4L A4 Firebird White w/T-Tops *SOLD*<br />**NEW CAR**<br />2004 White Cavalier Coupe<br />2.2l ECOtec 5 speedComment
