5.7 Hemi Exhaust Upgrade
I have been listening to an ever worsening exhaust leak since I bought it. One broken passenger stud became two followed by a blown gasket. A few weeks ago the driver's started leaking. Couldn't stand it anymore. I bought some headers last year hoping they would work.
After taking apart a lot of under the hood quagmire, the skid plate, transmission cross member and cat y pipe, my brother and **** remover extrordinaire began taking out the studs and bolts that remained. Once he got the manifolds off, he removed the 4 broken ones. We then tried to fit the passenger header. Unfortunately the collectors are massive at 3.5" and almost 5" at the flange so it hit the frame. I saw two SRT8 Grand Cherokee being parted locally so I inquired about the manifolds. Ballony eating turds wanted me to buy the engines to get them. A local wrecker didn't have any but gave me the number of a US wrecker that did. Guy was awesome. Pulled them, gave me deal and shipped them same day. Now I just need to wait for them to arive.
We noticed that the muffler was leaking too so I purchased a Flowmaster 70 from a local speed shop. I hate drone because I am getting old so I didn't want to run a Super44. I was going to leave the resonator but hearing the Super44 audio clips posted I think I can cut it off with the 70 series being substantially quieter. I will update the progress once I get the SRT manifolds.
