Exhaust sound question

[geoffsgt]

Does anyone else's exhaust tone change from day to day? There are times when my Bassani pipes have this beautiful throaty deep rumble cruising around, makes me absolutely love them, and other times its just kinda boring and/or raspy. Its got a few different tones, hard to describe.

Does everyone have this problem? I'm guessing its weather related, but I'm not 100% sure on that. Is it possibly a Bassani thing, or maybe poor installation?

Setup, as it says in my sig, is Bassani from the headers to the tips, with cats.

Never had a sound difference in my setups, besides after first break in. I have run full exhaust (LT Headers, O/R Mid, Catback) and always encountered the same sound, whether its summer or a cold Chicago day. It does sound different at RPM variations, but that always depends on the setup.

I know my car gets a little louder after its warmed up. And some days its louder than others, doesn't change tone though. I would think it has something to do with the temperature outside, density of the air, moisture in the air, etc. I dunno about the changing tone. Does it sound different when just cold vs. hot, or day to day differences?

The best sound I get is on cold dry nights, but that's not to say it doesn't get quite when its cold, or doesn't get loud when it's hot. It seems almost random.

And yeah, it's a different sound. One is much more defined, and loud. The other is raspy, airy... hard to describe... and not as loud. Just doesn't stand out as much as the louder one. And the most recent mod, the headers, were put on like 10k miles ago, so its well broken in.

I'd really like to get it to sound right all the time, cuz when it does... damn, it sounds good. Almost hoping its an install problem, so I can fix it. Otherwise it means I'll be unhappy with my exhaust 60% of the time.

could the cats be the variable? I mean if the cats are cold than it might sound different verus them being steaming hot.
