Any update on being able to re install the tunnel brace?

What size 2 bolt lap joint clamps are needed? All 3"?

Theses do not go up high enough in the tunnel. I did find the Halo Super cars one that fits larger exhaust. I just think that this is a basic kit vs a well bent system. You might be able to call Speed Engineering and just get the front pipes.

It came with all of them and I did not see any size difference. If you are buying the 2 bolt kind then the 3" will fit the who thing except the connection to the stock muffler.

I just got around to installing mine. I'm disappointed in the fit... Hangs much lower, tunnel brace won't fit, Very close to driver side diff cooler lines... (I moved them out of the way). I had cat delete pipes from other companies that fit much better in the past unfortunately you can't buy them anymore.
I did try to install just the front pipes first with no luck

Now for the price of this kit you do get a lot. I just wish they made it fit in the tunnel better.
The kit comes with 8 3inch band clamps and three 2 3/4 band clamps. The smaller clamps go on the reducers at the muffler, and on the driver side at the cat

I ordered the Halo Super Cars cross brace and loosened all of the clamps and installed the Halo crossmember then tightened all of the clamps. I will weld one of the joints and use the lap joint bands on the muffler side.

The fit could be better but to get the secondary delete and x-pipe for under $400 is not bad.

So the Halo cross brace actually fit. I was waiting on a reply from the dealer on how much further the Halo drops below the stock brace. Can you elaborate on the what joints you will be welding and where you are using the lap joint bands ?

[manders500]

I will weld the x-pipe to the pipes going to the muffler and use lap joints on the muffler. Here is the Halo installed

I had this kit on my 2018 SS 1LE, I also thought it fit poor, cross brace didn't fit as well. After getting it hot you'll have to go back and tighten up the clamps some more. I had issues with it leaking at almost every joint. I could smell exhaust in the car all the time, its an attractive system but going to go a different route with my ZL1 this time. Hope it works out for you guys.

We just scraped out the internals of my cats, which leaves only the small cat back mufflers. .

I bought the Halo brace and mine still hangs to low, Unfortunately. No time to work on it for a couple of weeks but I will try to figure out a solution. I'm considering Flatting the section at the brace slightly

How does it sound? I ordered the kit for the second cat delete. I already deleted the second cat, but I saw this and wanted to add a little more sound. Just curious how you like the kit.
