The car is basically an autocross car driven once in a while. No restrictions on exhaust in my class. GT Spec is half the price of the TI. One is dual exit one is single. Thanks

 

Since you didn't list noise or weight as concerns, sounds like you should just flip a coin to decide.

 

If there is no restriction and you do not daily your S, then the Tomei hands down. Will save you a ton of weight, only down side it is super loud. But no restrictions, so.......lol

 

I agree Joshua I had an invidia on my Subie and I always got a speeding ticket because it was loud and attracts so much attention. But again the Tomei comes with a silencer how loud is it with that on in terms of db?

 

Glad you asked. We actually made a video of my S2000 with the exhaust. With and without silence / test pipe. You can tell for yourself. But it is still loud with silencer.
