93 b18c1 hb,wich exhaust is performs better and is either of them reasonably quite (i'm leaning more towards the hiper ,piping is smaller .i think i wouldn't loose as much on the bottom)anyone have ant expeirence with either,thanks!

 

I've had both...each exhaust have their own distinct sound. The Fireball comes with an optional silencer which the Hiper does not. The Hiper emits a deeper sound while the Fireball is a little more high pitched.

 

any problems with clearance with the hiper and wich do you think performmed better

 

I honestly thought the unique design of the Hiper would result in clearance problems, but it's been fine so far. Of course, my car is lowered very slightly via Comptech Sport springs (approx. 1.0").

I'd have to say that the Fireball is a better choice if the car's lowered 1.5-2.0"

Seat of the pants dyno couldn't identify which was the better exhaust in terms of performance.
