View Full Version : Exhaust question

07-09-2002, 05:44 AM
Something I've been thinking about...

I already have a copy of the GReddy 3" downpipe. If I use this and hollow out my cat and keep it bolted up to my stock exhaust, will the car run bad? I don't want to keep it like this for racing, but just for everyday driving. If I did this I would buy an electric dump valve that fits in place of the cat when I want to race. I just want to make sure the car will run OK at stock boost under normal driving with the stock exhaust.

I'm trying to keep the car as stock looking as possible.

I have a 3" downpipe and a 3' test pipe going to a stock exhaust. Note I just ordered an apexi n1. It feels like the car cannot ge rid of all the gasses. It feels like the car has a huge bottle neck and it does.
