magnaflow question

jaredthomas27 · April 23, 2012

hey guys, im wanting to put a magnaflow exhaust system in the truck. i was looking at a catback stainless steal system that looked pretty good. well it was going to cost about $650. i am in college so my budget is tight. will i be able to just buy the muffler and take it to a shop and have them do the pipework that way im not paying for a bunch of stainless steel pipe, but instead galvanized? will it sound and perform the same? I am also planning on buying a stainless steel tip if i go this route. Thanks.

Just buy the muffler and tip. Make sure if you can, find the correct offset so it will be easier for the guy welding it to fit it without cutting any factory piping. That is exactly what I did with mine.

This may be a stupid question, but what do you mean by offset?

Look at your stock muffler. The inlet and outlet tubes aren't perfectly lined up with one-another, they're offset. Try to find a muffler with this same design....it will make the exhaust guy's work easier. And yes, you'll be just fine with using stock pipe and an aftermarket muffler.

Just go to the exhaust shop that will be doing the install and pick out the tip you want and tell them to replace the factory muffler with your desired length of muffler. They will figure out all the offset and fitment stuff for you.

I cant find the magnaflow muffler that comes with the exhaust system i am looking at as a stand alone muffler. there are some that are close but have a length difference. The whole system has a muffler that is 22" but the only stand alone mufflers that have the same other dimensions are 18" or 24". WHat kind of difference does the length make? Thanks for all the help so far, im a newb when it comes to exhaust systems.

the shorter the muffler the louder it is. i have a 22in muffler. the stock muffler is 25 inches. so the shop had to add a little piece to make the stock pipes fit (i kept mine). the one i got is http://www.magnaflow...e=main&id=10014

edit* i went back and looked at the set up you want. just keep the stock piping and change the muffler and put a tip on. cost me 160$ total.

edit** this clip sounds just like my set up. http://www.youtube.com/watch?v=Djd84pLVxzk

thanks for the info and video scz! I noticed you got the 5"x11", would that be quieter than a 5"x8"? THanks yall so much, learning a lot

Yeah, the longer muffler will be quieter. I have a 24" and I love it. It rumbles nicely, but isnt obnoxious with a lot of drone. But, it will growl quite a bit under a load. Like I said, I love it.

If you will notice on the Magnaflow FAQ page, the shape of the case has no effect on sound. The only factor that will effect sound is case length.

should be a little quieter because its its a bigger muffler. I had a 2 door tahoe before i got my silvy. spent a lot of time on another forum. i came over here last summer and i have learned so much from being here. Im in college too, so i understand the budget problems you face

Clemson is where its at baby! And to answer your question just get the muffler and tips you want and take it to a muffler shop and let them do it, thats so much cheaper... I got true duals on mine with no muffler and i love the way it sounds
