I want a system that has a nice rumble at idle but roars when i open up the throttle. Does the Bassani, SLP or Flowmaster fall in this category? Also what if i just changed my mufflers for some Flowmaster 40s? What sound and performance should i expect?

 

With only mufflers dont expect much gains a catback is the way to go. As far as what sounds better its just personal taste. Listen to these sounds clips and decide.

I have flowmaster 40 series weld ins. They do sound nice during idle & WOT.. BUT they drone like crazy at highway speeds.

 

SLP is the sound you're looking for man!

 

If your future calls for replacing the complete exhaust ( like headers and a mid pipe) Buy a cat back that will sound good with future parts. I made the mistake by buying a cat back that sounded great with the stock headers and mid pipe ( Flowmaster American Thunder). Now I added a SLP catted X-pipe and it sounds too raspy and drones like crazy at 2000 RPM's. :hmh: If I had it all to do over again I would have ordered the SLP Loud Mouth.

Ps. If you want a slightly used Flowmaster Cat back system I have one!!

 

I love my single chamber flows but it does drone at highway speeds or thats what my wife says The single chambers are pretty loud at wot and sound good at idle.Will eventually put on a o/r x or h and then it should be screaming

 

thanks. appreciate the replies.
