ive searched and read posts about the mufflex 4" cat back system and have read things like "they are too noisy" what do you all mean by this?

does it rattle a lot and hit underneath the car? or is it "noisy" meaning its loud?

 

Its a loud exhaust. It is a tight fit in between the floorpan and the axle, and it might rattle some, but you won't notice that much over the actual exhaust note. They sound awesome IMO w/ a Spintech muffler though. I know several guys w/ them and I personally don't feel they are too loud. They are loud yea, but if you want a loud exhaust for a high HP application, they are great.

 

I love mine. Nuff said .

 

Ditto on that. I love my exhuast. Now I just need to motor to take full advantage of it

 

Yeah it's quite loud. Much louder than the previous 3" systems I've had. Especially with my single out Flowmaster...

 

another question...
how is the ground clearance?? my car is lowered approx 2" and will it fit with a ford 9" rear end?
