Exhaust tips change sound? i always wondered if exhaust tips changed the sound of the exhaust not by alot maby just a little depending on what they are. i'm just talking like 3.5' to 4' pipes, or dual tips, i herd that the stock z28 lt1s/ls1s exhaust tips are the loudest the way they resonate the noise. don't know if its true or not, i have 3.5' tubes on my car and im getting my 80 series flows taken off and putting GMMG on 
will 4' tips sound different at all from 3.5 with GMMG

I would disagree and say that tips certainly have the ability to affect the sound.
Most of the sound I would guess is controlled by the engine and the rest of the exhaust. But if you think of an old Grammaphone they use a trumpet to increase the volume of the sound. A different sized or shaped trumpet would affect the sound. Maybe not change it par say but certainly alter the volume.
Also, I've seen it in person, or rather heard it. Many years ago when I still had the STOCK 2.0 in my TR7. It had the stock exhaust which had a rear box silencer woth the tailpipe straight off of it. Anyhow the weld failed on the tailpipe (mildsteel) and I simply pulled it off. The exhaust was the same, the silcencer was still in perfect working order, only it no longer had a tailpipe, but vented straight from the silencer to the outside.
It was noticable louder and more racey sounding. I was quite staggered to how much difference a 4" long peice of straight pipe made to the sound.

Re exhaust tips. I totally agree with your post. We had a 70 Olds Cutlas and when we installed the OEM megaphone tips the car did sound slightly different.

No problem then.I've used it as my DD for several years and has been really good, except for blowing up the diff a few months back. But then again it ain't what you'd call stock. It has an aluminium V8, Weber 500 Carb. Basically the doors and boot lid are the only stock items now on the car.
