anyone have any mac catbacks on their 5.4? how do they sound? thanks

 

I got one on my 5.4, it sounds mean, like a 5 liter mustang. It gets nice and loud at about 2k rpm

 

Advanced search using titles only, typing exactly as this *mac* will give you many results.

 

what kind of set up do u have?

 

stock replacement. I got to welded on b/c the guy who owned the truck before me backed into something, bending the tip completely closed, made the truck run like crap. They ship fast and the lady who answers the phone is very helpful. They will make you whatever u want.

 

OP, did you do the search?

 

where do i search it?

 

The tab above on the right, click it, then click on "advanced search". In the box, enter "MAC" and then select "Thred titles only". You should get some exhaust threads to check out.
