dragging a pipe

[eggrollfor2]

Hello friends I am new here so let me start by saying hello.
Reason I'm here:
Well I've had my 02 jeep liberty now for maybe 6-7years and this year when I put it into 4wheel drive I felt and heard aloud bang and then grinding so I stopped but it in 2 wl drive and even went into reverse to hopefully take it out of 4 it finally came out but now it sounds like I'm dragging a pipe in 2wl and even worse in 4. I'm thinking its my cv axles but I'm just not sure and replacing parts that arnt needed financially right now isn't in the cards. Thanx for your time and any help I can get -E

The rider often believes that by reducing back pressure in the exhaust system the engine will also increased power. This is wrong. As a resulting of changing a stock exhaust system to Drag Pipes, most engines promptly lose 5-10% of the power the engine produced.
