I just installed my new AAM exhaust, header-back (although i had the tps before this weekend)

Anyway, i have three problems that i am going to complain about, and need to solve urgently because they are pissing me off. I have an 07.

First of all, the midpipe is resting on the rear cross member (sorry if im callin it the wrong name - its the black support on the frame infront of the diff.) During idle, and throughout the rpm band, the midpipe hits this, and rattles very annoyingly. Any ideas about how to fix this? maybe raise it up or put something in between the two?

Second, the tip is REALLY close to the bumper. Im afraid it will melt it. Any suggestions about this?

Third, the idling RPM dropped significantly. it rests around 400 rpms and fluctuates uncontrollably. it is like the engine tries to fix it all the time but never succeeds. Any ideas about this? im afraid this wont go away without a tune. (also, the car feels like it will stall so much easier because of this)

Thanks for your help in advance.

BTW, the exhaust sounds amazing haha. and it picked up a lot of power. i just need to go get on a dyno.

 

bump

 

Is there a joint near the brace where it is sagging? I had a similar problem with Turbo XS, a solution I came up with that has worked for me and other memebers is to take something like a socket, wedge it upright between the brace and the pipe. Now that this area is supported, crank down on the bolts joining the Y to B pipe connection. Once you have cranked down to gorilla specs, use your ratchet to tap the socket out from between the brace and the pipe. I've put about 800 miles on my car since doing this and not a single rattle or buzz.

 

alright that sounds like a good idea. ill give that a try today when i get home from work and see how it works out. thanks man.

 

just work with it, loosen some ish and align it up, you can use shims too.

 

dissconnect your battery and try and reset your throttle body and if that wont settle your idle you may have to get idle air volume relearn.

 

get some nice thick washers on top of the rear cross support to lower it some...I had to do this on my HKS TD exhaust due to having Headers and Test pipes which made it slightly lower...And ohh yeah goto the dealership and get it done for free...Just say your idle is too low and it should be covered under warranty.

 

alright. im getting under the car today to fix the rattle the best i can, so ill try to fix the idle as well by disconnecting the battery. if it doesnt work, ill go to the dealer. Thanks for the help.
