I also have JIC full ti and it is ultra light. I haven't hit the dyno since installing the vortech SC, but I can tell you it flows much better than stock, regardless of FI or NA.

I run around with the silencer out all of the time. It sounds like a F1 race car when the supercharger is spooling at 8-9K!

I had an old lady walking down the road near my house nearly have a heart attack when I came rolling by at 30mph.

 

for my $$$... spugen dual ovals-
great looks, great sound and added hp at the ground-
what more could you want?

 

I had the JIC Single--with the silencer in you can say goodbye to hp gains after 6K rpm.

With the silencer out....I'm not really sure what, if any, power gains there were--it was so loud I had difficulty concentrating on how fast I was going.

There was a HUGE loss in weight, though.

 

lol! CmiS2k!! that is funny as hell! yeah, that exhaust is extremely loud. i love it though, i think it sounds great.
