    Hi all - I am thinking of installing a magnaflow replacement muffler for my '04 2.4L. I'm hoping someone out there has done this mod and knows the right model number magnaflow to purchase, and if there were any issues with install when keeping the tailpipe (notably, making up length differential b/t stock and the shorter magnaflow). Thanks!

    I can't personally help, but you may want to look in the 4 cylinder section. Lots of muffler info there.

    I realize this thread is old but I keep ending up here when searching for a Magnaflow muffler for my 1st gen. 2.4 l. Having an answer here would help a lot of people.

    Anyways hopefully someone has an answer for us 2.4l guys. I see that people like the Magnaflow but no one seems to know that size they have.

    What I'm really looking for is the correct 2.25" inlet/outlet center/center muffler and a range of sizes that would sound stock, and some sizes that would sound a bit louder without pissing off my neighbors or the cops. I plan on chopping the old one out and putting a new one in. I'd do a cat back but I can't find one for our trucks anywhere.

    If you have a link that would help too. I'll dig through it and put the info here for all of us that end up here.

    typically once you have the inlet/outlet diameter and locations figured out then with straight through glasspack type mufflers like magnaflow the muffling is then controlled by the length. shorter=louder and longer=quieter, you just have to figure out what length you need to achieve the sound your lookin for. if its shorter than the stocker then you simply add a section of pipe to make up the difference.

    I may end up going with the Flowmaster. I know, as Ed mentioned, people like the Series 40 for a more aggressive sound and the series 50 for a nice sound without being too loud.

    I've seen more fans of the Magnaflow sound though and the dyno shows that the Magnaflow do a bit better although exhaust adds so little that I'm buying for sound, not performance. If I knew what sizes were being used on the 2.4l I'd go this route but without a point of reference I'd be playing the trial and error game, which would get expensive.

    I haven't seen the Borla mufflers yet so I'll have a look at them.

    I called Magnaflow and they recommended the 5"X8"X18". He said that I could expect it to be a bit lowder than stock bout shouldn't be enough to bother people. If I wanted a bit louder I should go with the 5"X8"X14" but cautioned that some may find it to be too loud. I'm not sure how conservative they are on their recommendations but Ill find out when I put one in. Ill post back in a month or so when I get it installed.

    5"X8"X18"

    I ended buying Tue 5x8x18 and a Harbor freight welder. I'm happy with,how the pipe sounds.
