Default Re: On the Road Again - Purple ZR-1 Road Trip to Utah

I was coming here to post the same questions as Jeff. I don't find the ZR-1 to be noisy at all. Yes, you are not cut off from everything mechanical as you are in a modern car, but it's hardly what I'd call noisy. In fact, I wish there was a little more sound from the exhaust.

Thanks for sharing your trip with us. It certainly has inspired me!

The previous owner said it was stock, but I'm doubtful. I haven't had much of a chance to look just yet but I'll try this week. At 75/80 mph the wind, tire and exhaust note were just too loud to really even listen to the radio. It was better/worse depending on the road. I will say that the seats after 13 hours were just amazing...no discomfort at all during the trip, which is amazing.

The exhaust note at normal cruising speeds is glorious. It really sounds like a big block to me.

C4s and most Corvettes are a bit noisy with their fiberglass construction and large tires right behind your head. A loud exhaust (or one that drones) will aggravate that. If you could post a picture of your exhaust tips we could probably tell if your exhaust is stock or not. And if you have an aftermarket exhaust without catalytic converters it will be louder than stock. I was able to mellow out the sound of both my ZR-1s and my current Z06 by installing the sound deadener Dynamat behind the seats and in the hatch area. Only a slight improvement but noticeable to me. (some folks have removed the seats and installed it throughout the cabin). On my Z06 I got my Dynamat and asked the local Best Buy's audio installation department to install it and they did it for only $100 but they really should have charged more. --Bob

This isn't my car, but it's what the exhaust looks like:

Maybe we should open a new threat on that topic to not highjack this great threat here.
In Evans threat he says "Sold my Steel Blue 391 ZR-1...". I understood this as an indication of a modified engine, 391ci instead of 350. Am I wrong? If so this might be an indication for more engine growl.
My bone stock 91 is a great highway cruiser even way beyond 80 miles an hour (thanks God we're still allowed to). My 335 Michelin rear tires are barely noticeable, as are exhaust and engine at cruising speed. Of course all this changes when you floor the pedal, but not on steady cruise. She's not at all a silent car but far away from requiring earplugs on long runs.
Excessive tire noise might (but doesn't have to) be a sign of hardened or worn out bushings or worn tires with sawtooth profile.

Agreed...sorry, wasn't trying to derail the thread. I read the whole thing prior to picking mine up.

First of all I'm SO excited to have signed on and seen that you two were back on the road. It's literally the reason I signed on to the forum just now was to see if that might be the case. Excited to read the chronicles this time around.

Secondly, I wish I'd signed on about two months sooner....... I would have seen your trip start and I'd have been able to TELL you that Indianapolis is F**KED. Indiana state flower is the orange road cone now. Living here has been difficult this year.
