Pre-cat delete, options....

[Kgnast]

Down pipes, piggy pipes (gutted pre-cats), or cut out the precats and weld in pipe/flex-pipe in place. Down pipes cost cheddar, piggies take a while to gut out. Who's just deleted the pre-cats by cutting them out? If so, what did you use to bridge the gap? Pipe or flex-pipe?

Secondary cats are bigger than primary.
Here is a video http://www.youtube.com/watch?v=RxnYH3JONkE both cars got straight pipes, one of the cars both cats deleted, the other one only secondary.
Zmey installed his mufflers back and it sounds very nice.

Only took me 45 minutes per pipe to gut......just sayin.

Only took me 4-5 hours per pipe to gut......just sayin.

Sounds about right...

Yep...about a half hour per side to gut the pre-cats...Pipe in the vise and a big hammer and chisel or steel rod...and just keep smashing...I had gutted precats, no cats and SE mufflers...sounded perfect with no drone...
