yep, i took the muffler off. And one of the resonators. the whole thing(from muffler back) comes off in one piece w/ the removal of the nut on the engine side clamp of the muffler. Too easy. sounds viscious too. I can feel a little more top end on the motor, now also.

 

Is there still piping going through the back? If not, well.... good luck.

The loss of backpressure.... and having all the gases re-enter the engine, well... not good. At all.

 

piping thru the back? explain. there should be a lot of back pressure from the manifolds and the resonator, not to mention that poor excuse for a y- pipe (a set of 2" pipes strangled by one 2.5" pipe.) Catalytics provide some back pressure also. You think my check engine light will come on if I'm fn it up?

 

thats the whole point in free flow kits is to lower backpressure, mine I did the same exept I added a 90 and a crome tip which brought it out infront of the rear tire

 

that made sense, t bird. after market kits reduce back pressure and thats exactly what i did. reduce not eliminate. Ericemery, what do you mean "flip it"?

 

I think he mint trip it

 

right, trip it, shoulda figured that out. you guys got me worried now, but i'm hooked on that rumble.

 

mines the same as yours with just a little extra pipe and never had a problem with it.
