to sum this up:
a 4" tip shouldnt make much difference then a 3" tip if your running stock pipping

Is it staying on stock piping? If so, it's not going to be very loud:

Not sure if you have an I4 or a V6, but that's a Magnaflow race series oval muffler with a 4" tip like you bought on stock piping. At idle and light driving, you won't even hear it.
yea it will stay on the stock piping, and i have a V6
it will add some noise tho rite?
Did you listen to the sound clip? Yes, it will.Quote:

slap the thing on and if its too loud, go back and tell the shop to slap on another resonator too.
Not being a dick or anything, but IMHO a canister muffler will not sound good on a non-turbo I4... I really don't know what to say. Any domestic oval muffler or any chambered muffler will sound good but a straight-through canister style muffler will sound like ass on an N/A 4G64. If you want a deep, quiet, and smooth (not raspy) sound, look elsewhere beside a canister muffler.Quote:

performance is something i am just starting to get interested in, altho i still have many plans/wishes for body work, but that will happen when the time comes, i am a noob at performance but hope to learn alot soon

i'm getting the magnaflow race series 14851 on monday as well and will be putting it on. warm helped me decided on that expecially with that sound clip. i saved the clip to my comp. lolQuote:

sry for the mixup
RRE recommends magnaflow race for v6, and magnaflow street for i4:

thanks
what do u recommend ??? in open to other options I mean if a canister is not for my car then I'm not gonna be upsetQuote:

^dont worry about using my thread, its cool bcuz its the same topic kinda
double post
I have a canister muffler on my i4 with a short ram air intake and it doesnt sound bad.
If you're dead set on a canister, get the street series Magnaflow that Reelax posted up.Quote:

whats the difference
You have an OEM-style oval muffler if I remember the for sale thread. A canister muffler is round like a coffee can and typically has less sound deadening ability.Quote:

that has a 2.25 inlet which if im not mistaken stock piping, so what do i need to do if i end up going with a 2.5 piping ???Quote:

it's about the same but a lil more quietQuote:

Which makes sense to me. If you're getting the velocity out of the tuned header, and just hold that velocity and increase flow behind that, the motors going to perform the same or better.
When I get my system done, its going to taper up from the 2.25 of the RPW header to a 3" and run that out back.
It kinda goes along with the knowladge that most all engines with a quality tuned header do not need an exhaust system past that, and make more power without one. Thus racing engines that run straight headers.
but there has been no mention of a header here... the 4g64 at 2.25" mandrel is plenty unless it has heavy NA bulidup and a well designed header... 2.5" on the 4g64 is pointless w/ stock header unless you are going FI or heavy NA (w/ headers)... at which point you would jump to 3" cat back in either case.Quote:

You should keep the exhaust the same diameter as the downpipe because every transition in size creates unnecessary turbulence. The exhaust needs to be tuned to match the primary and secondary piping diameters. What's more important is scavenging and you're going to really screw up the exhaust pulses with an exhaust that large on an N/A application. 3" is way too big for an N/A 3.0 L, no matter how wild the setup is.
ok i don't know what FI means but what I got so far is to stay with stock piping unless I go boost or N/A
FI = forced induction in this context (don't get it confused with fuel injection). AKA boostQuote:

I would never suggest putting that on a car that is not turboed/supercharged. On a side note installing exhaust/muflers/headers/intake/performance chips/filters/thicker sparkplug wires/NAWS!! sticker without actual ecu retune/engine work is PURE a waste of money. if you aren't boosting, save money and do it the right way. I don't care if your car can make a farting sound your still as slow as you were before. Thats that, Thats all i have to add to this. BTW this is comming from a person that had all those upgrades done multiple time.
I'm looking to go FI but I'm still reading on and I figured my car will look nicer with a muffler and I will need the muffler when I boost anyway
