Im looking to build me own catback system. Minus the gato. Ive been lookin around and see that its feesable with some mandrel bent tubing and lots of good welding. Can anyone give me tips on what diameter tubing to buy or anything else, like a really solid, not farty, not too loud but a little raspy, muffler? Also, when welding, what about the flanges, connecting to the headers from the pipe, do those need to be customized or retrofitted somehow? thanks

to stay legal with a cat.
get a highflow cat gut out the honeycomb...... and then replace the inside of the cat with a smaller pipe one that fits snug. then cut the pipes equal and weld them together. In the end you have a pipe straight through ur cat with out losing the visual of the cat. so when you get pulled over for being to loud you can look i have my cat and everything.

just a way to keep it legal ....
hope this helps
