I have a question about cutting out the CAT when straight piping.<br><br>1st: Does leaving the CAT on dramtically reduce the loudness/sound quality benefits?<br>2nd: I do not want to install the straight pipe myself. However, it's a $10,000 fine for a muffler shop if they cut the CAT off. Would it be damaging to cut off the CAT and then drive to the muffler shop?<br><br>Thanks.

 

You won't hurt anything by driving w/o the cat. However, you might want to check to make sure that nothing is in the line of fire, and perhaps put a deflector of some sort at the end of the pipe.<br><br>My cat has its own little pipe, and can come and go with band clamps when I need to test.<br><br>I removed the straight pipe and put on a small muffler. The truck is noisier with the muffler<br>george
