Exhust question
I need a suggestion. By way of background. I bought a straight pipe setup homemade by a forum member. I am running this through the sock H pipe and blown our cats. This car is rarely driven on the road though I may do One Lap of Am next year where straight pipes will drive me nuts before I get to South Bend. It is loud!!
Currently with the straight pipe setup it is fun on the track but I would probably get a black flagged at a track with DB meter. I have ordered a long tube header system and will be getting a tune for the rear cats and to figure in some of my other minor engine mods. But as you know a good custom dyno tunes cost $400-600, so I would only want to do it once and not have to re-due it if I change the catbacks.
I am thinking the straight pipes are out, but maybe if I can find a used ZO6 ti catback it would may make sense.
So my question, would the zo6 catback behind my long tube headers without cats, be a good power producing setup? I can't imagine I would gain much more power with an after market catback system, plus the weight savings can't be ignored.
Any thoughts, and anyone have some ti catbacks laying around?
Thanks,
Jay B

Get some turn downs. 30* from AutoZone
and point way from the sound meter.
Most DEs dont have sound testing. A few tracks Roebling Road may test at DEs if they think there is a car that is too loud

The sound under heavy acceleration is plenty aggressive but won't drive you nuts on the road. Try the C5 Parts For Sale section. I see the C5Z mufflers over there regularly.
