SRT exhaust manifold install today!

uploadfromtaptalk1408626009166.jpg

Jeep is on the lift, mid pipes and stock manifolds being ripped off now. I cleaned up the inside welds on the SRT manifolds a bit with the dremel (should have worn gloves, got steel sparkle dust everywhere, very painful). Didn't go too crazy as I didn't want to weaken the welds too much. Didn't need to make the EGR port as I've got a 2010 hemi with VVT. So excited, I've been wanting to get this done for months. More pics to follow, any and all advice or input greatly appreciated!

Re: SRT exhaust manifold install today!

Good to see you went ahead with this. You won't be sorry. It'll be a noticeable difference in performance, especially if have a low restriction, straight through muffled cat. back built to go along with them. Can't wait to see you first impressions.

Also, if you can, post up some pix of the stock 2010 manifolds vs. the SRT's you're using.

Re: SRT exhaust manifold install today!

I have the Gibson stainless cat back on there now. The plan is to chop the stock cats out of the y pipe and weld them into fabricated mid pipes. I believe that will make the ~2.5" stock cats the new most restrictive part of the system but didn't want to risk throwing codes with aftermarket cats. Thanks for the encouragement!

Re: SRT exhaust manifold install today!

I should get a call from the shop within the next hour, I'll snap some comparison pics of both manifolds side by side

Re: SRT exhaust manifold install today!

Heading over to the shop now, he said the steering shaft was going to be "very close" to the header on the drivers side. Has me a little worried... Any thoughts?

Re: SRT exhaust manifold install today!

Day one is complete. The SRT manifolds are bolted in. My local shop let me hang around a lot and it was very clear that this isn't a "do it in the driveway over the weekend" job. Things to note: 1) 5.7 VVT Hemi (09 and up) still need the EGR port ground into the manifold. You'll notice in the pic above that my mechanic welded a small strip on the outside of the header where he ground out the EGR channel to add support (also kind of ground a small hole straight through and wanted to patch it. Whoops!). 2) had to remove the steering column for ease of installation for driver side header. It's back together and has plenty of clearance. 3) I purchased SRT exhaust manifold head bolts and I'm glad I did. You can see in the pictures how the stock bolts are longer and stock manifold is thicker, using the SRT bolts will provide the same net bolt length and will prevent bottoming out.

Tomorrow is the down pipes. I picked up o2 sensors at the dealership that had longer wires than normal (18" vice 12") they are electrically the same but have one of the 3 plastic guide rails on the inside of the electrical connector (female end) offset from the stock ones. We are going to shave that offset guiderail off of the male end if we find we need longer wires but we'll try and fit the stock ones first.

Thanks for following! Hope this helps someone somewhere! More to follow tomorrow.

Re: SRT exhaust manifold install today!

When I had my custom headers built the guy had the same problem with the steering. He was able to move something slightly with the steering shaft and it now clears without issue. I've had my headers on for a little over 3 years now, and the only trouble I've had was not retorquing the bolts and ended up blowing the No. 1 cylinder flange gasket. Had to pull both headers and re-gasket......a real PITA. What size is the collectors on your stock and SRT units? The early stock ones are 1 7/8 in. and my header collector is now 3 in. As you can see, you'll see a huge difference in performance with your new setup.
