Installing the Summit 2.5in A body exhaust

Are you guys still happy with this system? How does it sound?
Will these bolt up to the stock manifolds?
Is 2.5" a limiting factor for a 5.9L Magnum? Not sure if I should invest in 3"...
I just sat on hold with Summit for 15 minutes...perhaps I will give them another try.

These systems are for headers and areisted to work with Hooker Comp. headers.
2.5 inch exhaust pipe is a good size and will handle 400+ HP.
At 3 inches, your good for 500 HP
These are general guide lines not set in stone.
What is the goal or current power level of the 5.9?
What is the intended purpose of the car?
Mostly street or track. 50/50-ish?

Thanks, Rumblefish.
The car is going to be street...maybe an occasional trip to the strip down the road. It's a "Magnum300" (mild) and will stay that way for a while... it sounds like 2.5" would probably be fine.
I read a test showing almost no benefit from headers on this exact motor...but it sounds like I might need to save up for them anyway if I'm going to go this route.
At this point, I'm looking to get this car back on the road before mid-summer and I'm looking for the simplest solutions...impatience never pays off.
I am installing the summit kit this week, I bought TTI down pipes for my stock manifolds.
Gets some pictures up!
Here is the TTI manifold pipes, on the bench, they fit under the car with no issues.
I checked fit, welded standard header collectors on them, the pipes come out past the transmission cross member.

Here is what the summit kit has in it, I removed the large box of clamps to take the picture.
Small update, have not been working on the duster much, it as been 90+ degrees every day after work, but here is a pic of the TTI manifold pipes, with the front hook up pipes on the Summit exhaust not installed.
I will have to make a piece to attach to the head pipes.
The reason I did it this way is I can take the down pipes off in necessary to allow more room for clutch / motor changes.

Of course, I have the same system, it f'in rocks!
Where did the OP disappear to? Haven't seen him around in a couple years..
Resurrecting this in hopes you have pics of your install? Difficult to find documentation on 340 hipo Manis, tti head pipes and Summit 2.5" 680144.

Let me look, I should have some.
I found a few pics.
Basically used a header flange welded to the TTI down pipes, and connected them to the header back Summit 2.5" kit.
All joints were welded to prevent leaks, which is a PIA, because you have to put the entire exhaust together, tack it under the car, then remove it in sections to weld on the bench, this will prevent any leaks.
The only part that is clamped is he mufflers, also throw away the clamps that come with the 2.5" kit, they are garbage, buy some heavy clamps from NAPA.
I have still not decided if I am going to trim the ends back and install turn-downs.

Thanks for pics! Great idea with the header flange on the down pipes. Looks like they were added on without being shortened prior to welding? I would think you shortened the pipes leading to the muffler?
I just added the flanges to the ends of the down pipes.
If you look at on pic, I actually had to add about a 6" section to the drivers side pipe after the flange, because the down pipes are shorter than long-tube headers.
