I have a bassani off-road x-pipe with flowmaster 40 series and I am not happy with the sound above approx. 2300 rpm's. Sounds like a tin can, and has kind of a raspy sound to it. Is this because there are no cats? Besides the tin can sound I am very pleased with the note. Help please!

 

yes...the catless pipes will sound raspy...if u wanted no cats....the h pipe would have been the way to go...or even the SLP midpipes cause u cna interchange between cats and no cats...

 

Alot of it is the chambered muffler's.You will always have a drone with them inside the car.

 

I bought the car with the current exhaust...if I had the choice I would have gone with slp's!

 

x's with chambered muffs sound like crap.

 

mine was so bad i almost took them off and went with magnaflow. i added bigger and longer tips and i have no drone(3.5". 18"long)
mac O/R prochamber and flowmaster catback.

 

You should have gone with an H pipe in the first place, X pipes dont make a mustang sound like a mustang in my opinion
