Like to hear from those who put a 3 in complete exhaust in a Dart (70) .......

I bought the TTi complete exhaust for my 72 Dart, have yet to install it though. But the 3" they make fit my 73 Challenger like a glove.
This is good to hear, I also bought the TTI 3” for my ‘67 Barracuda. Waiting on the new engine to be completed then will install.
Hope someone who has installed these chimes in.
