whats the best size exhaust pipe for N/A im thinking of just going with 2 1/4'
im using an rksport 4-2-1 header and Borla Muffler and Magnaflow hi flo cat... its going on a 2.4L
what size pipe should i use and what resonator should i use(brand and size for resonator please)
i would say no bigger then 2.25 and just get any cheap glass pack for a resonator they all do the same and the size is upto you on how you want it to sound honestly. you may not even want a resonator

04 sunfire auto, mid 15's n/a, and still going
i want a nice deep sound but still want it to be loud..just not ricey loud - which i dont think ill have a problem with havin it sound like rice with the setup i mentioned
get your magnaflow cat part number 94035
as far as a resonator, get as large of one as you can. event has a 30inch res, mine is 24 or 26 inch

you should read that article he posted too....you could learn something as i just did
i wouldn't use the resonator....i have a borla exhaust with no resonator or cat and i think it sounds great....i get alot of compliments...
i would def use a resonator. remember noise doesnt make power, power makes noise

it may sound great on your car. but on mine or anybody else's it might sound like crap

Im a Xbox 360 fanboy...and damn proud of it!!
yeah im going with a resonator

any recommendations on which kind? and pls tell why you recommend that brand
i go all magnaflow, 6 years and 7 setups all of my parts have been magnaflow. reliable, quality, and comes in stainless or aluminized steel.
resonators and cats = MAGNAFLOW!
I was a retard, and now I'm permanently banned.
alright then i think i have my setup all figured out
rksport 4-2-1 header
magnaflow hi flow cat
magnaflow resonator ( maybe 24 inch? )
Borla Pro XS muffler
2.25" mandrel bent pipe
brand new O2 sensors ( just so i can say everything on the exhaust is brand new lol)
and havnt decided on the tip yet but im keepin it around 3"
debateable subject. I have
a header 2.5" down pipe and 2.5" Cat and a 2.5" 29" resonator to a Cross Flow (Camaro muffler) Dynomax Super Turbo. My resonator is Cherry Bomb Glass pack. I didn't have the time to find a magnaflow resonator plus i was getting my whole set up done for $75. out of town so pick up the glass pack which is usually what a resonator is.
I am not sayin that 2.25" is not optimal but this is a debateable subject. Some will show Dyno's done to prove 2.5" is better but they that will bisputed because the tests were not run on the same day.etc..

2.5 is going to give you more hp. For a 2.2 id say 2.25 but for a 2.4 you should go to 2.5. I havent posted on here in over two years but hasnt everyone seen the dynos on isuzuperformance.com? They ahve a dyno on there proving 2.5 is better.

As i said you are going to see both sides. Someone else is most likely going to come and say it is to big. I went with the 2.5" i have no dyno number but it was an improvement. i had a 2.25" before but when i put on the 2.5" I also put on a header so i have not idea how much gain because the whole exhaust system was done.
