the place that is performing tuning to my "s", is willing to make me a custom titanium 4 inch exhaust. they would make it look just like the j's racing 70rr but 4 inches.

does anyone have any sound clips of a 4inch exhaust?

right now i have a dual 3incher without cats and its loud just wondering how much louder the 4 would be.

 

Im running a Vibrant 4" race muffler, its more of a resonator. If you can find a real muffler in 4" it shouldnt be too bad. But its definately much louder than 3". Ill have a dyno clip on Monday.

 

thank you tinker.
