the u-bend delete is very simple I had mine done when i changed to magnaflows my exhaust shop didnt even charge cause i was having other work done
JUst tell any basic exhaust shop you want the u-bend at the rear o2 sensor straight piped with a bung for your o2 sensor
Or you could always get a downpipe and that should solve the problem for you as well.. zzperformance and many others sell them catted or not.
and as said above read as much as you can about the mods and car in general. it will help in your modding and keeping a reliable engine.
