Is there any way possible to install LT headers and not have to get a tune? I will eventually get a tune after I can do a cam swap and a few other things, but I have a broken manifold bolt and want to go ahead and put on LT headers instead of messing with the factory exhaust.

I just installed LT's and my tune is not set up for them and it runs and drives fine. I am getting a re-tune but I don't think you should have a problem without a tune.

Mine ran like **** for a few days after the long tubes but now it runs fine. I'm still waiting to get a tune.

Hey are you going to have to customize the exhaust with long tube? I just have shorties but would rather go with long tubes.

you can run them without a tune and not have a problem...I didnt have a tune for about 2 or 3 months...

You need to modify your y pipe. You can order most long tubes with a new ory tho so it will bolt up any cat back or stock exhaust.

Order the longtubes with the y pipe from the same company... and it will bolt up to your existing catback... i ran mine for years without a tune.... on longtubes ory and a cut out....

You'll notice alot if you do the tune at the same time.
