Do the cars have a lot of gaseous fumes coming from tips?
just wondering,,,thinking about opening on up-for maximum flow.

I have the LTH and 12" resonators, when I had my Z tuned it was running lean. It is recommended that you have your care tuned with headers but not necessary. There is an unburned fuel smell with this setup but its not as bad as a test pipe combo. For noise level I think its perfect, its quiet below 3k and normal driving. Cold starts and driving fast is pretty loud.
