Do the cars have a lot of gaseous fumes coming from tips?
just wondering,,,thinking about opening on up-for maximum flow.
hopefully the 18" res. will tone it down a bit.
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.

How loud would you say it is compared to short tails with a catalytic converter? I want it louder but not full straight pipe loud. Mainly because of all the crazy rasp you get.

Sweet.
Just can't decide between non resonated/high flow cat/z1 headers

Or FI long tube headers/12" resonators

bias aside I would say FI LTH over Z1 if youre doing headers.

Z1 you got $900 in the headers then $250 in TPs you're close to the price almost as the FI LTHs which I think are a better choice for whatever money they cost.

if it were me i'd go LTH/12" res with CF mufflers. seems like a good fit for your taste from what you've listed previously. good power and sound from the LTH plus a bit of cabin reduction with the 12" res and I personally love the CF mufflers. the bit more exotic sound and the look of them just seal the deal.

Completely overlooked the cost factor, definitely worth getting the FI LTH then. Thanks brother

anytime

you really can not go wrong with any FI product. plus their customer service is second to none.

also if it's not loud enough just call tony and tell him you want the FP option lol

Noop, it is just about perfect. Very exoctic sound when your on it with stock cats. I wish I knew what a non-resonated CBE sounded like with resonated HFC's. Haven't been able to find a video on that.
