I was looking at this kit for my car and it states that it has 2.5" tubes for the exhaust. But if you read the info on the summit racing site it says that the tail pipe is 2.25. So this is not a true 2.5" exhaust then. Why do they advertise it as 2.5" if it aint? Anybody ever use this kit and am i reading it wrong or maybe is it just a typo? I am wanting a true 2.5" exhaust from beginning to the end of the tailpipe.

I did and you are correct! Also the header pipes neck down at the manifolds. I ended up ordering replacement head pipes from show-cars.com and did noy use the rear tailpipes. Only used the front pipe and wheel well pipes and mufflers. The wheel well pipes solved my problem of the pipes hitting the emergency brale levers on the calipers for the rear disk brakes. I did get a good deal $550.00 for the kit from ebay so it was worth it but at full price I don't think so.

Here is a link to the 348/409 2 1/2" kit aluminized.

Well man i like the fact that it was stainless, held together with clamps and not welded. the price was reasonable too. Also it had lifetime warranty. Well i was gonna modify the front pipes anyways cause im running longtube headers.

What did you use for the rear tailpipes?

Mine is a little different in the back. My pipes come out thru the rear valance so I used S bend pipes to raise them up.
If you go the normal below the valance you can use the ones with it or have some 2 1/2" straight pipes made.

This has some good info in it -

Also there's some info in my build topic about the kit. All in all its a decent setup, just takes a little massaging to get everything where it needs to be.

Use a Shafer exhaust system -with 2 inch tailpipes

tailpipeshttp://shaferscl assic.com/i-22627281-1962...

(or a Show Cars system 2 1/2 inch systems and other options -they both fit ( I installed both) and "factory original exhaust system mounts "(all factory 61 to 64 frames are drilled for factory exhaust system mounts>>>>> ;) like these from Show Cars
https://www.show-cars.com/cgi-bin/commerce.cgi?pre...

Why weld on the car or frame ??-- for mounting the exhaust system (you can also buy individual factory exhaust mounts from Show Cars).

Here are a couple pictures of the orginal pipe out the rear from the kit and the "S" pipe I used to move it up to the valance instead of below the valance.

How did you hang the pipes? Did you use the existing tabs that was welded on the exhaust? I see that they come with 2. One set towards the front and one set towards the rear. Or did you used orginal style hangers? Like pvs409 mentioned i really dont want to weld these in place on the frame?

I used the factory frame mounts that bolt to the factory frame holes on 2 sets of original reproduction aluminized tailpipes that exit at the rear bumper

Show Cars sells tailpipes that exit at the rear bumper and use the factory mounts. I can post pictures.

Here is a couple of pictures. I welded a 90 deg bracket on the rear of the tailpipe where there was an existing hole in the frame to mount to, notice I used a piece of the hanger leather between the frame and pipe as an isolator.

I also took the wheel well tailpipe clamp assembly and took out the leather and welded the 2 pieces together. This brought the pipe up a little more out of the way of the tire and emergency brake caliper arm.
It makes it more rigid but I have not found it to be a problem.
