I can't get my downpipe hooked up to my cat for a day or two, is there anything that can happen to my motor? I'm trying to avoid driving my car due to the noise level and a slight oil leaking from the return line problem.

 

what can go wrong: you getting pulled over by a cop for a noise ticket, then getting busted for the parts on your car and for not using a catylytic converter (big fine!).
Other than that, running open DP is probably safer for your car than more restrictive piping + cat.

 

watch for these things:

boost creep
running lean
traction problems
police officers

Other than that, go for it!

 

Not even worth it man.

 

You guys act like I'm doing this because I want to. I have an appointment for wedsnday, that the soonest i could do, that's why I'm avoiding drinving my car.

 

keep it WAY out of boost
watch for cops. if you do boost, someone said it. watch fuel and boost creep.

 

Well, I intemded to run off the cat for the track in a week or so, you still think fuel would be such a problem? The AVC-R seems to do a good job of watch ******* the boost so I'm not too worried about that, but about leaning out!
