Who has one?

Im looking for the 4" to 5" tip. What performance gains do you get? I want something loud, more of a semi truck sound. But louder than stock is fine.

Anyone have any expirences?!

 

I know it isnt magaflow , but My buddy has a 5'' Hypermax exhaust on his truck with a 4'' downpipe , and it sounds as close to a 18 wheeler than any other diesel pickup I have heard......

 

I have a 3" downpipe increased to 4" pipe, then to 4"MagnaFlow muffler, then 4" pipe to exit in front of rear tire. Since at the time no one sold a turbo-back system for my year of truck I bought the downpipe and the muffler from web sources and the rest(pipe,fittings,clamps) from Napa. The system sounds incredible especially over 2000 rpm. The MagnaFlow muffler gives the exhaust a great resonance. I've only gotten compliments from others on mine. From what I understand from reading previous posts on this site is the the difference between 4" and 5" exhaust systems is negligable.
Just my 2 cents.
