is there a bolt on cat i can get so my lude wont make so much noise. it has a str8 threw pipe but its a lil to loud for my taste now so, where can i get one that will deminish that loud sound.

 

you can get a high flow or go to a junk yard

 

Is the straight-threw piping welded on or bolt on?

If bolt on, I purchased this CATCO catalytic converter for my car when I found out the previous owner had hollowed out my OEM one.

I have not had any problems with this cat so far after putting around a thousand miles on it and have passed emissions easily. If you decide to go this route, you will need to purchase new hardware (bolts, washers, nuts) to bolt on the cat.
