Exhaust System To Increase Hp

[94Celsior]

Which exhaust system / mufflers would increase horsepower? I was recommended to put a flowmaster kit on my 94LS400 but i dont want to loose the silence and peacefulness of my ride. :chairshot:

i'm gonna use HKS products when i will get enuff $$. i will change whole Y pipe to get more power and make it lil louder:)

ive seen HKS exhaust systems on an LS before, but i didnt like the look and i dont want my car to sound like a ricer. Flowmasters has different stage kits for sound, so it wont sound like an F150. im replacing my whole piping system from the headers back. the has potential to be quicker but with the restrictions, it doesnt have a chance. i dont care about the sound, im into power.

if u go to www.lextreme.com, he has some sound and video feeds of the different exhaust modifications he's done along with some other members. there are extensive forums that address ur question on that website. i think he did a resonator delete mod that made the LS sound like hot rod, it was very interesting
