Is it safe to run just a downpipe and take off the stock cat and the catback?I'm just testing it out to see how it runs,but I wanted to make sure that it's safe before I did anything really stupid..

Safe to let it idle (it will be LOUD!), not safe to drive -- you will boost creep like a ****.

LOL actually... me and my friend drove around town like that for a couple of days because we were tesing a few things.

Heres a video of how it sounds (note: the coolant seals are gone so it sounds like bridgeport) http://youtube.com/watch?v=O0FGoZ9HmP4

.....and yes... its THAT loud

I was quite hesitant about doing this because of boost creep and when it backfires the flame might hit gaslines, gastank, etc..

i wouldnt do it. Almost all cat-less rx7's shoot fire...lots of fire. I would prefer the fire not to be shooting underneith my car toward fuel lines.

I'd say not to do it. Afterburn("rotary backfire") will roast the underside of your car pretty fast.

Might as well take off the DP to

or the tank (!)

plus breathing the fumes
