True duals and exhaust set up
Thanks in advanced
cat back - term typically used for an aftermarket exhaust that replaces the stock unit from the catalytic converters back, following stock or near stock routing. on the later lt1s and the ls1s...they are more like Ypipe-backs...since they don't replace any of the ypipe. they start at the merge of the ypipe and go back.
Xpipe - a crossover setup that is used for true dual pipes. it merges the exhaust from each side of the engine, then splits it back up into 2 pipes. helps equalize pressure between sides, boosting power a little bit
cutout - a muffler bypass setup. basically a Y in the pipe somewhere, one leg goes through the muffler, the other can be uncapped an allows un-mufflered exhaust flow. nice way to boost performance and sound for CHEAP.
what are you plans for the car? budget? tolerance for noise? all that will dictate the best exhaust for your application.
