Default deep sounding stock muffler normal?

I just took my performance muffler off for a stock muffler. The car still sounds deep when accelerating lightly. Is this normal for a stock muffler or should it be really quite on a 1995 suprercharged bonneville?

That will depend on the muffler. Each brand is a bit different. Also depends on the cat and rez. Is teh tone just deep, or is it also loud?

Its just deep. The guy at the muffler shop said it was a Gorlick'* stock replacement. When he said stock i was thinking that it would be like it was out of the factory. I cant remember but I think it was alot quiter than that. It really sounds just a little less deeper than the low sounding Raven exhaust I had. When driving and just a little pedal pressure it sounds exactly like the Raven. Low deep sound. Did this muffler shop take me?

I have a 95 SSEI and a couple of years ago I replaced the muffler. NAPA did not have a stock one for my year and could not get one. They said they were were discontinued. They had a a stock muffler for a 94 Bonneville non supercharged. The upside was that it was a stainless steel muffler and as such would probably outlast the car. The muffler shop had to do a slight modification to the exhaust connector to put it on. I noticed right away that it had a lower rumble than the original muffler. So it seems that the original muffler for the supercharged cars help to make them quieter. I am no muffler expert but this was true in my case. I suppose you could ask if the muffler that was installed on your car was specifically for a supercharged Bonnie. You could also verify through a dealer if the mufflers are different . At any rate I do like the sound and I have seen no reduction in performance.

Well I forgot to mention that I did install a Magnaflow high flow cat a couple of months ago so it may have deepened the sound a little but going from a bad cat to a new cat its hard to say. The muffler made the biggest difference though. I was pleasantly surprised.
