Yesterday my friend and i installed my lsj exhaust onto my ls. It sounds great even for a stock exhaust, but i was wondering if anyone had any issues with rattling when they installed their exhaust. I'm pretty sure we're gonna have to go under the car again and see why its rattling. Even though i just messed with the hangers to pull the exhaust farther up, it seemed to stop rattling. Any input is greatly appreciated!

 

mine fit like a glove and has never rattled. idk what it could be. and whatpart of KY you from?

 

I'm from Walton, its like twenty minutes from cincinnati

I had a rattle about a year after installing a full header back lsj exhaust... the culprit? There is a solid metal piece inside the downpipe flex section that had un-welded itself some how. I welded it back in place and the rattle is now gone.

 

Do you have an auto? If so look to see if the Cat is hitting the sway bar.

 

anyone have any vids of what the lsj exhaust sounds like on the LS? I have a buddy that will sell me his lsj header, DP, and stock lsj catback for a really good price. Only thing is that i have that SAI deal on my car, and not sure if it will affect anything other than throw a CEL if i dont "delete" it in the computer....

 

nope its a manual

edit: Actually i did the intake mod if u count that...

 

im trying to look for a lsj exhaust manifold back but not having much luck, any thing u guys can recommend. Also i see a ton of people talking about there cobalt air box mod can someone explain exactly what it is?

 

Well i'm pretty sure i fixed the rattle, i took two extra rubber hangers i had from my stock exhaust and put them on the new one. It seems to be working.

 

My "fix" didn't really work, anyone else have this experience when they put the lsj exhuast on?

 

My Tsudo rattled against the rear axle/swaybar assembly, look under it without it jacked up and see how close they are.

 

I looked it seems like its the piece that goes over the axle to the muffler. I have to get a better look
