H pipes are used for tone control, they balance the backpressure. the
location is figured out by locating the hotest point on the header pipe and
installing the crossover there. it is usually located a ft or so back, right
about mid-point of the tranny. most people just put them right behind the
trans. an easy way is to use an X pipe.
Summit has a racing/street muffler for half the price of the Flowmaster. we
put them on my sons elcamino sound is nice and mellow until you stomp on it.
glass packs have a definite sound, tinney to me. but very old school.
limited life on the glass packing
i installed the Summit mufflers on my apache, last year, haven't got to hear
them yet.
you should weld your exhaust system with minimal slip joints like behind the
mufflers or use header flanges and bolt the joints together. my truck is 1
piece welded, dumping down in front of the rearend. legal since they end
past the passenger compartment. use a hole saw to cut for the H pipe and
weld everything together.
