help w/ my evo2 exhaust
i just put it in on saturday, there is like a knocking noise (like if you used a stick and hit it on a tin can) from underneath the midsection of the car.
it's loudest when the car is cold, then after its warm it makes the sound only during certain types of bumps.
otherwise, it runs and sounds great
please help! what's going on?

It might be banging against a heat shield. Make sure that there's no heat shield within a 1/2" space from the piping. When you hit a bump, it might just be b/c the exhaust is on rubber hangers and it's swinging a bit into the shields. If so, bend the heat shields away a bit.
It'll be worse when cold b/c the engine idles at a higher rpm causing more vibration in the car and from the engine through the exhaust. It's most likely a heat shield.

Dude! I have the greddy evo2 exhaust and i have the same damn problems!! It rattles against that little mid brace and it hangs noticably lower in that area between the center of the car and the rear axle. I was thinking myself that the design of the axleback must be too long or something. It bugs me, i might even switch exhaust, i just really like the sound tho, i dunno what to do

if not, then the greddy folks should listen and take notes....
it's a great exhaust but it does not fit as well as it should! i'm sure they don't want ppl reading this....
