So I just got my flowtech headers in for the truck. On summit, it said they have a 3" collector, and they do, but the connectors they gave me neck down from 3" at the collector to a 2.5" tube that the rest of the exhaust gets built off of. This was NOWHERE on the part description. So the exhaust kit I ordered (also from Summit) wa a 3" x pipe kit. Naturally, 3" exhaust kit wont connect to a 2.5" exhaust tube. So I figure I have two options:
1) Return the x-pipe kit and mufflers to Summit, and try to see if they can get me the new stuff by Saturday (I was hoping to fab the exhaust this weekend)
Or
2) Go to a local exhaust shop and see if they have a 3" to 3" collector connector.
Thoughts?

Seconded. The expense and hassle of trying to return everything, with the *end result of a smaller less throaty exhaust*, I think not, if the local shop can get him set for a few bucks.

I think that's my first option. Especially because I want to be able to do it all this weekend. I shall make calls to exhaust shops tomorrow.

Velocity is not just at the head pipe. That is where it is greatest. As exhaust gases cool, they need to continue to keep the momentum, to get out of the way of new, hotter gases coming from the combustion chamber. As they cool, they lose that ability, so to offset that, you must have increased flow speed. By reducing tube size, you increase flow velocity and hence speed of flow. That is why header wraps are used. More heat, more velocity. Hope this helped.

Yea I understand. And to be more straightforward with it, you're suggesting keeping the reducer and getting a whole 2.5" kit?

My thought would be to adapt down to the 2.5 inch, unless you have the performance mods to go to the 3". If you do, then by all means, go to the larger dimensions. (Sometimes, 2.75 inches is a better consideration.
Call one of the exhaust mfrs. tech lines, they can usually be of great help on matters of sizing. Good luck.

Yea I was planning on calling summits tech line tomorrow and talking with them about which exhaust size I should run as well as if they could get the new stuff out to me by the weekend.
