ZO6 Exhaust
So really it comes down to price if you ask me. the going price for a Z06 axle-back is 400. I wouldnt spend more.
There's no improvement in performance and the slightest bit of noise from the Z06 pipes. Way too much work for no particular benefit.
Nothing makes HP on the catback scene. Your best bet is to shoot for noise if that's your liking.
I just replaced Corsa catback installed buy the previous owner. I did not care for the sound at idle, sounded like a gurgling walrus. Decereration sounded sloppy, popping. Awsome at WOT. No drone while crusing.
I went with Z06 TI catback. Imacculate condition for $450.00. The fit and finish are excellent. The welds would make any metal man want to cry, they are absolutly amazing for titanium. Alot quieter than Corsa. A much more tuned sound at idle, WOT and deceleration. Best bang for the buck IMO. About fifteen pounds lighter and will probably last forever to boot.
The Corsa I replaced was installed with the stock intermidiate pipe ( H pipe).

Sorry, it won't make any additional power, either. It's only charm is that weighs a lot less than the standard hardware and you can sneak home at 3 AM without waking the neighbors.

The tips also look 200% better than the crap GM gave the stock LS Vette..

The manifolds use a different right AIR pipe and oil dipstick. These will need to be replaced or jury-rigged when installing the Z manifolds.
The midpipe for the '98 will not mate to the Z manifolds either, so the Z midpipe will be required for sure with the Z manifolds.
Absolutely not worth it to install the manifolds, midpipe from the Z. although the Z manifolds will net about 5 HP over the '98's, the cats/mid-pipe gain nothing; so the work and AIR/dipstick hassle is not a good return on labor/hassle/parts at all.

Although, if you spend a lot of time at Wide Open Throttle at high rpms the mufflers start to change their tone at idle. Sound gets deeper with more resonance in it. Can't hear the difference in the car but people always asked me how come my C5Z always sounded so much louder than others. That type of operation tends to turn the chrome tips blue pretty quickly so if you want shiny chrome tips you have to go to the Harley Store to get some chrome polish. After a while the heat also tends to break the welds on the inner outlet pipes and you have to have them welded back in place by somebody who can weld titanium (not many around).

With headers & X-pipe, in combination with Ti's, sound great, especially at 3/4 throttle and up. Weight savings is a nice bonus.
You see them on CL all the time for $300-400.
