Straight Piping the C32
Hi all,
Right now my exhaust setup is as follows: Eurocharged shorties > primary cats > MagnaFlow 12468 dual in/dual out muffler > tips.
So I have no secondaries or resonators. This was ideal when I was driving it every day but now I am away for college, I would be able to deal with loud idling and cruising since I only get to drive it when I'm home every once in a while.
I'm thinking of ripping out the MagnaFlow muffler and putting in a simple X-pipe. This would leave me with no mufflers or resonators so it would just be: Eurocharged headers > stock primary cats > X-pipe > tips.
Does anyone have any experience as to what this would sound like? I want it a lot louder but I don't want it to sound completely unrefined.
Thanks!

do not do it. It'll be way too loud and NOT in a good way.
However if you want it a good bit louder replace those low flow bottlenecks called primary cats with some 200-300 cell cats to let those headers do their job.

man, that's a bummer. it sounds way too unrefined in those videos, like an f250 with a muffler delete or something.
i live in california so touching the cats is something i don't even want to venture into. i guess i'll have to live with what i have. i would put two glasspacks side by side in place of my current dual in/dual out muffler but i really want to keep an x pipe in for the performance benefits.

thanks for those vids man. it's funny, i like the second vid with the 12468 the most and that's what i have! i still would ideally like it to be louder though. it sounds too raspy for me without that magnaflow to sort of mellow it out.
i'm wondering if a shorter magnaflow muffler would do the trick. i'm sure it would be louder but i'm not sure if the sound would become higher pitched or not. my thought would be that it wouldn't because the only real difference would be that the exhaust would be in contact with the packing material in the muffler for less time in the shorter muffler than it would've in the longer muffler. so this should, as i would think, just allow less muffling. i could swap the 12468 for essentially the same muffler but either 3" shorter or 6" shorter. i just don't want to diminish the deepness of the sound now.

thinking of pulling the trigger on a magnaflow 11379 to replace the 12468. the 12468 is a 5 x 8 with an 18 inch body. the 11379 is a 4 x 9 with an 11 inch body. from what I've heard from magnaflow officials, the shorter the body, the louder the sound. they say the length doesn't have much effect at all on the pitch (deep vs. tinny).
now I just have to jack up the C32 to see if it'll allow a 9 inch wide muffler. any thoughts?

Case Exterior Length (in.): 24.000 in.
Overall Length (in): 30.000 in.
Thickness (in): 5.000 in.
Width (in): 8.000 in.
It made HUGE improvement over the drone master and fits in the drive shaft tunnel pretty well...only hangs down about 2" and I haven't scraped it on any driveways or speed bumps.
Sounds great at idle and WOT but its still too damn loud between 2k-2500k. I'm going to dynomat my trunk in the somewhat near future and if that doesn't improve things enough I'll have my exhaust guy re-do the cat back in 2.25 instead of 2.5".

that would likely be too quiet for me. the 18 inch magnaflow muffler i have now (12468) is too quiet. that's why i'm likely going to pull the trigger on the 14 inch or 11 inch. it's just hard to tell if it will fit since it's one inch wider (9 inches versus 8). they don't make anything shorter than 18 inch bodies in 5 x 8.
EDIT: looks like there should be enough space to fit the wider muffler, especially if it's pushed frontward more. pulled the trigger on the 11-inch 11379 and will post when i can comment on how it sounds.
EDIT 2: called magnaflow to double check that the 11 inch that i ordered (11379) still has the x pipe in the muffler. he said the 11 inch does not but the 14 inch (11386) does have the x pipe. for those who may be unaware, x pipes generally make more power in a true dual setup and drastically reduce rasp. this is why it's a must for me. so i ordered the 14 inch and will be returning the 11 inch and i will update this thread when i get it installed friday evening (as long as it fits).

because the c32 lives in california where they're really strict about the primaries. i would love to though.
anyway, installed the 14" 11386. It's a squeeze but it's not too bad. i haven't scraped it yet so i don't think it's any lower than the 12468 was. in terms of sound, it's a tiny bit louder, a bit throatier, but honestly not much difference. i wouldn't recommend spending the money if you already have the 12468 because the difference is so small. i'm still happy with it though!

Hmmm, maybe you should try a setup similar to mine (video in my thread) to get some more noise except just leave the primaries in. No sec. cats ----> y-pipe ----> 3" single in/out muffler ----> y-pipe branching to the tips. I think the reason you're not getting louder is due the perforated core plus the x-pipe that's inside the muffler. Kinda works as noise cancelling, atleast that's what it sounded like to me when I had it. More refined puurrrr and throatier with less rasp to it.

If that's Godly, im throwing my SS bullets off that car asap.
Godly in a world of scooters maybe, cant even hear the exhaust at idle until you walk behind the car, then it sounds meh, little ricerish.
First black benz vid down lower is prolly the most pure sounding of all on this page. kudos to that guy

Thanks for the tip lol, not my first trip to a forum before and not hard to find critiques on this forum or any other, its kinda what happens on forums and opinions kinda get asked and given often, and its really not a big deal to disagree with how someone else views a video. lighten up already, get a v8 if you want real duals and the sound that goes with it.

yes but what is the point of true duals without a deep dual sound? you do realize that you will not sound like this right? cause when your talking about cutting out res and straight piping or race piping its obviously what your trying to achieve

the sound of my setup is plenty, plenty deep. deeper than my brother's modded c63. i abandoned the idea of straight piping and whatever you think "race piping" is.

you want to sound like this (525rwhp).. but will sound more like that other like some of the vids do. There is no replacement for displacement remember what your engine really is when you take away the sc. hard to achieve deep dual sound.

You don't know what a race pipe is but im ignorant? umm yeah doubt that, your trying to make a ricer engine sound like a muscle car , get real. and stop playing the innocent role when you directly commented to me cause you didn't like my video comment.
