Anybody familiar with a 3" exhaust system for a 71-71 Riviera? TA-Performance only has them up to a 70 Riviera. I have a set of TA Shorty headers and I'd like to compliment them with a fresh 3" exhaust system but can't find any pre-bent sets. Thanks1
I have a 72 and everything I've read says that without the engine being heavily built 3 inches is too big.
I've put in a race cam, bored it out .30 over and put some higher compression pistons in, I hope that's enough to justify some 3" exhaust.
I hadnt found one either, i was considering one of the flowmaster U-fit kits... http://www.amazon.com/Flowmaster-81...1401463231&sr=8-3&keywords=u-build+flowmaster
There are no pre-made systems for the Boat tails. I made my own from mandrel bent tubing and straight pipe.
