Anyone put in a chambered exhaust on a 350/200 with 2" pipes?
Can the square tips be used? Is it only available in 2-1/2"? I am thinking of doing this to my '72.

I put chambered on a 70 BB car some years ago, and I am getting ready to put chambered on a 70 SB. I am not sure, but I think I used a 2 1/2" sustem on the BB car, but the pipes at the back of the car were sized to fit the standard tips. The 70 SB car has the stock 2" manifolds and everything will bolt right up, including the tips.

I have the Allens chambered II on my 72 sb. Just as the fctory exhaust, it goes from 2 to 2.5" pipes. The system I ordered was for the 73, which has a 2.25" outlet. When I ordered the system I ordered the 73 tips. Kit came with all the clamps and hangers. The fit was very good, didn't take long toistall. It sounds great, except for a drone at 45 mph, which is rather bothersome to the ears. With the top down, it sounds like a sidepipe car.
If interested, Allens Stainless is in Indiana, great people to talk to and work with.

I have a 350-200 also and I got this set 603-858

IIRC they start at 2" and then go to 2&1/2 a few inches from the stock manifold.
The tips are turned down and I installed 2 stainless steel extensions.
Can't answer about square tips.

So 73 square tips are made for 2 1/4" pipes and all 70-72 square tips are made for 2" pipes?

Custom bent mine in a buddys shop, used 2.5 inch pipe and 18 inch resonators(chambers). I also have long tube headers sounds great. I recommend having a shop build a set for your car.
