im thinking of just running a straight pipe and dump for my exhaust setup, since florida has no cat laws or emmision testing and it sounds good and not to ricey, or just a mufler delete, prolly 2.5 or 2 and a quarter, what do you think?
I have 2.25 from the cat and it sounds good. But mines not the usual setup, Most people go for the Muffler/Tip exhaust. My muffler is in front of the rear wheels under the car. Then it Y's out to 2 - 4" dia x 22" long slanted chrome tips.
well im actually removing the exhaust resonator and welding a pipe in place of it, so ill still be running stock headers, both stock cats, stock piping, and stock muffler. so hopefully it wont sound too bad, if it does, ill jus reweld the resonator back on :/
only thing not stock is my sri which sounds deep and im jus hoping it follows threw the exhaust
okay thats for the info, ill have to run just headers and 2 cats no resonator till i can get to a shop or get a buddy with a wlder to weld teh piping, so itll sound dumb of course for a day or two.
what if you hollow out the (i guess its a resonator) either right before the flex pipe or right after it. its the one right before where the cat back gets bolted to theexhaust. ive been thinking of doing this since i got my cat back exhaust.
has anyone done this? and if so how does it sound?
not many newer cars contain teh stuffing stuff thats in mufflers/resonators, a resonator is basically allowing the waves fo exhaust to enter and it boucnes back meeting another wave cutting thr exiting wave in half, which reduces sound. and air flow presumably. im just welding a pipe in place of the resonator.
the thing further back is a second cat, i think that's what your talking about, and hallowed out it makes the car sounds mean as hell with the resonator off.
no the second cat is right after the header bolts to the exhaust and the resonator is jus after it, its about a foot long and its about an inch more wided than the exhaust pipe.
no need to hollow out the cats though, i think newer cars are already hi flow. so doing that would only really hurt it other than for sound.
What about just taking the second cat out, or does the empty shell help with resonance. Also Smiley those tips look like they should be on the back of a Pickup truck. I kind like them though. I am sure they sounded mean.
stiaight pipe is going to sound like bumble bees in a metal trash can extremely loud,i had it running like that for awhile and got tired of it, i added a magnaflow cat and i gained back my backpressure. and sounds deeper
i got it done today, took res out, straight pipe in place of it, has a deeper idle and better at lower rpms like 2-4k sounds a bit deeper, cant tell ina video though. not as loud as i thought itd be, prolly casue hte muffler iss o restructing.
yeah i didnt want it super loud, its really noticable around 1200rpms, pretty much cruising speeds for my roads. it sounds ncier than stock though and a decent weight reduction off my car, sucker weighed as much as one of teh stock alloy wheels. so prolly sound 20 lbs.
thanks for the compliment, and about your header, id go for one off ebay as long as it has an O2 sensor built in it like our stock headers, unless you dont mind a CEL, i wouldnt care becasue florida doesnt do emissions tests.
and a friend of mine bought a 500 dollars DC sports header from ebay for his civic hatch and an OBX header, same exact design, performed the same dyno, so id say 75 dollar ebay header ftw and just get upgraded gaskets and stainless steel bolts (unless they come with it of course)
yeah i like it,m your car makes me want to get black mesh wheels youve done so much, took everything off back to stock practically started over haha its crazy.
