this is my first time post.
i was wondering what is the best exhaust setup for ls/vtec..
my current setup is:
94 integra ls
b18b bottom block
b16a2 head
b & m fpr and gauge
dc cc 421 headers
skunk 2 cam gears
test pipe

i love the test pipe because of the sound when vtec kicks in, so i want to keep the test pipe in the exhaust setup, but i need a setup for daily driving, not too loud, but enough exhaust flow to not lose so much power. thanks in advance.

 

all depends on how much you're willing to spend.
first off, ditch the 4-2-1. i suggest a 4-1 with a 2.5" collector. after that you could go with an exhaust that has 2.25" or 2.5" piping. a good quiet muffler is Mugen but hella expensive. I've heard good things about Apexi World Sport, RS*R, and stock ITR as well. if loud doesn't bother you, theres Apexi N1, Greddy Evo, HKS hiper, Type 1, and Spoon N1(also expensive)
