2nd Gen Non-Engine/Transmission Exhaust noise

[Ken Roberts]

The time came to replace my exhaust system because it rotted off. So I buy a 4" system, straight pipe, turbo back. I searched the forums for noise issues.

I see that it WILL be loud and will resonate at highway speeds. I order it with and without the muffler. I can send the muffler back if it is unused.

So I mount the system as a straight pipe.

YOWZA!! This is loud! Sounds like an angry cement truck. Kinda cool though.

I left it this way for quite some time. I pretty much got used to it.



Then the wife got to drive it. :-laf :-laf

Boy did she have alot to say!#@$%! The nicest thing she had to say was "How on earth do you deal with the noise?"

That got me to thinking. Just how loud IS this thing?

I got out my trusty db meter and checked it. Standing in front of the radiator, holding the meter at chest height, it read 97db. At the tailpipe, at idle, 3 feet away from the tip @ a 90degree angle it read 101db.

In the cab at idle it reads 94db. At 75mph it reads 99db.

That, my friends, is loud. I think the muffler will be attached by next weekend.

That is loud. OSHA mandates a maximum of 85db for an 8 hour day. Anything louder requires hearing protection. Your hearing is definitely at risk.

I just want to know where I can get a dB meter.

Seems odd. The exhaust on my truck is sans a muffler as well and I don't find the truck to be excessively loud.



Then again, it's not a full 4" system. It looks like the stock pipe comes out of the turbo and then jumps to 4" around the trasnfer case. Maybe that has something to do with it.



And a db meter would be usefull as well...

I bought mine at Radio Shack years ago. They probably still sell them.

Yep. Radio Shack. Or in this case, a Pawn Shop. Made by Radio Shack

I just spotted a meter made by Scoshe at the local Wal-Mart. The range is 60-130db and the price was $24. 44.
