Just wondering?...........

 

You need to try it out and see for yourself. Just normal driving it ain't too bad. Pulling a load may be a different story. Where do you expect to exit the vehicle with the pipe? I've read that if it exits in front of the rear wheels it is a lot louder that behind the rear wheels and a little louder than stacks above the cab. Frankly, I didn't care for the noise so I installed an oversized muffler. It cost me about 25 to 50 degrees EGT.

 

I cut out the muffler and popped in some straight pipe, still exiting with stock tail pipe out back. with the windows up I cant tell any difference, even on the interstate. with the windows down it sounds great, you get to hear the turbo singing through the pipe.

I like it, windows are always down, esp. by any type of wall beside the road.

I put the new pipe in with those wide seal clamps, and cut out the muffler so if I need it I can do a quick swap.... and pass inspection.

 

Yeah, I basically wanted to know what the sound difference was between the having the stock exhaust with muffler and stock exhaust with no muffler (straight pipe). Sounds like there is a slight difference......

 

I would say a little more than slight but love mine. Def find myself looking for things to ride beside of to hear exhaust.

 

When you are passing someone, pulling a load, they will know the difference.

Mine was straight when I bought it. It is louder than others I have heard, but with the windows up I still barely hear it.

 

With the pass side window up it sounds normal to me. I have alway had the straight pipe since I got the truck(PO installed). Mine is the stock exit behind the pass side rear wheel.

 

I think you wouldn't regret having no muffler.Pulling a load you can hear it if you pass someone.but if you keep your right foot out of it,it will be quite as stock.jmo

 

Muffler? What that?

I have never heard a 1st Gen with a muffler. The only other 2 I heard had them straight piped.

With my stacks, rolled up windows, at 65, is the quietest. It is like a low hum. I can hear the engine at this point. At WOT, the only thing that was louder was a turbo from a 02 Chevy DMax with a straight pipe.

Look at the video in my signature if you want an example. Its still stock pipe just no muffler and it exits out the side right behind the cab.

 

Heck my truck came to me with no muffler and nothing behind where it went and it isn't bad in fact I sort of like hearing the turbo... idling at a stop in gear in my auto is a bit much so i'm going to straight pipe it back to at least in front of the rear wheels or perhaps a stack.

 

My Stans 4" with a muffler sounds the same at idle as the stock pipe hacked off at the transfer case with a 4" straight pipe that exited under the bed. I hated it straight piped while cruising on the highway. (annoying drone) With the 4" and muffler it sounds just right to me. Also, if hearing the turbo is your thing I couldn't hear mine as much straight piped as I do with the full exhaust.

 

I have the stans kit too, but at highway speeds I can hardly hear it, unless driving past somebody or near freeway walls or underpasses.

I wonder why you have an annoying drone? Is the pipe hitting part of the frame somewhere?

 

I can relate to his problem. The 89 auto is the 727, no o/d. Which means high revs at highway speeds. I recently eliminated that problem

 

It will be perfect.
