I'm thinking about picking up some ZO6 mufflers for my car to get rid of the B&B PRT's that are currently on it. They drone really bad around 1500 rpm and it drives my wife nuts (It does kind of beat your brains out). I always have to drive a gear lower than I would like to keep the rpms around 2000. They are also really raspy in a weird kind of way, kind of like a Mustang. Do the ZO6 mufflers drone at all? How about with headers and no cats? How much power should I expect to lose, and will I have to screw with the tune from the added back pressure?

No drone with headers, the only HP loss would be be from your ear dyno I doubt they would effect your tune.

Thanks, I didn't want to spend the $250 and waste my time if they still droned.

You won't lose any noticeable power, you will benefit and save a couple pounds. I have a set stored indoors with 12,000 miles on them if interested. I ran them with long tubes with hi-flow cats. Had a european note IMO

Dave concrete

No drone, very mellow until you lay into it, than they get a loud european pitch.

$250 is a good price also

I swapped out my Borla Stingers for TI a month or so back. I have had Borla's and BB's on my last 2 C5Z's and went back to TI's on both cars after listening to "drone" and not being able to carry on a normal conversation as well. I highly recommend the swap as I will NEVER change out my TI's again. They are light weight, have NO drone, flow extremely well (GM spent a good bit of time on development) and have a great tone at WOT all their own. Just do it and don't look back. No regrets. Enjoy the ride!

Of course the guy has had them for sale for 3 months and he just sold them a couple days ago. I had a chance to get them at New Years but just couldn't get myself to part with the cash due to building a garage.

One of the best mods is LT's and TI's.

Have LG Pro's and TI's. The combined weight is 21lbs.

The sound is well.. get a pair and find out..no drone..

The Ti's should not drone, but another option would be to consider an x-pipe. I had a set of B&B Route 66s on a previous C5 and the drone/popping was terrible. Installed an x-pipe and I would say better than 95% of those two issues went away.

81Ls1Camaro

I already have a kooks of road x pipe installed.

as for that drone - how much sound insulation have you done on your car? I did a bunch of work installing mass-loaded vinyl in the wheel wells, and the cargo area. Made a very significant improvement. It was a big job, but well worth it.
Still have not done anything in the passenger compartment.
BTW - I have a 2001 vert, MT6. Switched to the Ti exhaust. They are really light compared to stock, and have a smoother tone.

81Ls1Camaro

The previous owner had some sound deadening done when the did the interior, but I'm not sure how much they really did. Here are a couple pictures. The exhaust note is hardly audible but its the low frequency when around 1500 rpm

Sam Handwich

WELL, you won't get much help from more sound deadener.
Ti exhaust is a proven winner. I highly endorse it.

Do you still have the TI exhaust? I have the Borla and can't stand the drone either. Just let me know....where are you on the Island? Iam in NC the last 26 years. We bailed out of Syosset in 1990.
Thanks,
Carl

As others haved said, there is no drone at all with the Ti exhaust, but it's just too quiet for me. It has a nice growl at wot but I like some rumble at low rpm's and it's just not there with the Ti. They are super light and fit very well, though.

I've had the Ti exhaust on my car since I bought it. I've never had any drone with all of the many different engine/header combinations that I have had on it over the years.

81Ls1Camaro

Thanks for the input guys. I'm thinking about trading the PRT's for a set of Ti's with another forum member as we speak. The only thing I don't like as much are the tips, but I suppose those are replaceable.

DetroitPlac

The nice thing about the tips is you can get them to line up straight, and they look pretty good. A lot of aftermarket cat-backs have issues with getting the tips just right.

I personally love the Ti's with LT's. They're a tad on the quiet side, but zero drone, awesome tone, and really roars at WOT.

grantv

To a T how I feel. A tad quiet, no drone, amazing tone, great at WOT.
