I know this subject has been beaten to death and most of the information people need regarding HFC's can be found on this site, however I still need some advice.

First, if anyone has this set-up please let me know how you got rid of hiss and the rasp.

I understand that this is usually inevitable depending on your exhaust. A true dual setup should take care of alot of the annoying side effect of the install. If that does not help I understand an X pipe should take care of the rest.

My issue is that my set -up is similar to the OEM set-up



I cant utilze the x-pipe and at this point am pretty annoyed from the sound.. Car drives awesome but sound like sheet between the normal range of rasp ( 3000rpms).

Anyone have any suggestion so that I dont have to spend another G on exhaust.

 

Also the piping is 2.5 inches

 

Can I get some feedback on this fellas?

 

Looks like it has a standard size y-pipe? Why not switch to the Motordyne XYZ Y-pipe with resonator?

A much cheaper alternative is to simply replace that resonator in the mid-pipe with a more effective resonator or even another muffler in it's place. Any shop could do that.

 

What do you think about using this and just cutting the existing mid pipe and welding it in?
