sounds pretty good.. Should have went with the ultra flow.

Sounds good. These cars didn't run too bad actually, I got to drive one a few years ago and it ran pretty good.

No, a Grand National is American and never sounded like shiz.

689539 you right the 300M is not a car for race or performance... it's luxury and comfortable...big boat lol!but I love it. I modified my muffler just for pleasurit's the same engine in a prowler... but the prowler is a little bit faster! haha!

Sounds just like a Prowler.

V6s can sound awesome, look at the R32. but knowing this is on a giant 300M takes the cool factor away, since it's giong to be verrrrry slow and not even close to a performance car.

not bad

its not a i4 with vtec. its the other engine option if you don't pick the hemi. whats next, you going to say that a buick grand national is rice because it has a turbo 6???

sounds just like a dynomax should, yeah i agree wit usmusl get something besides rice

It's just hard to make rice sound good. Give it up!
