So today I was just wondering what my car would sound like with just a dp, test pipe and midpipe. So I took off my axle back and started it up. And I liked the sound of it. But upon driving my afrs would be normal 14-15's but at a stop sign it would dip down and act like it wants to stall. Did taking off the axle back have something to do with that? And it wouldnt boost like normal? Input please
