Is it possible to have bigger Engine (383 maybe) that would make power (over 375hp) and have a free flowing exhaust, that is quiet. Like as quiet as stock exhaust? cat-back, silencer, anything?

I think it would be cool to be able to be quiet and kick ***.

But then again I love the loudness too, just a theoretical question.

 

Get a Maremont muffler. Then get one of those electric cutouts at www.quicktimeperformance.com.

Nice and quite sitting at the light. Mustang pulls up next to ya. The yellow light for crosstraffic comes on. You flip the little switch, light turns green, and
WHAAAA!!!
you're gone!!!! :sillylol: :sillylol:

 

You might want to do a search on the Dynomax catback...

 

Yep. Not sure what to get though, I know when people have sleepers like old muscle cars,not sure of what setup they have though.

 

I should by that cutout thing, and mount that where my borla plates go, I can go from full open to full closed with a button.
