well the wife has started to complain about the car being to loud. so i wanna know if a high-flo cat will quiet the car down? or do i need to change the muffler out? my set up as follows 4-1 header 3" back no cat and magnaflow muffler any idea what i can do?

 

I cat will quiet it down quite a bit but if that doesn't do it get a new resonator for your system I hear vibrant makes a good one. I know when I put a cat back on with my setup it made it much quieter still loud though lol

 

thanks now need to go get one any ideas as to what brand to go with

 

Do you have longtube headers? If not ZZP makes a nice downpipe with a cat I have been very pleased with mine.

 

you can get a cat and get a muffler insert ( don't call it rice) it worked fantastically on my car .. they sell them on jegs, patriot auger muffler insert long as you have a straight part of the exhaust thats longer then 14" .. it's made for 3" ID piping as an FYI so if your piping is 3" OD you'll have to do a bit of grinding to make it work..
