resonators definitely. check out my 4.0

The 4.0 was unbeatable in indy car for years (till they quit making olds) I'm looking into droping in the 4.6. same everything, except 50 extra ponys.

strange how that happens. I took the resonator off my car and at first you could barley tell. over time it got louder and rapier and now its quite loud. whats that all about?!? anyway, nice cars I guess. 4.0L right? I wonder why they didn't use the 4.6 NS instead of making that motor just for that car?

yes resonators, clean elegant car.

It has slowly gotten raspier. I'm looking into getting a resonator now. Thanks for the the opinions

i've never heard flows sound like that before

Please do add the resonator. It won't take away from the personality of the sound. But, will quiet down the rattle noise it gives off. Just my opinion though, It's your car.
