So I have been scouring local fs sites for a midpipe but aren't having much luck. I looked on youtube and found videos of sedans with magnaflow resonators in place of factory ones. I really like the sound but can't find a part number for the magnaflow. I have a 03 sedan...does anyone know which magnaflow resonator works? Thanks in advance everyone!!

 

They add a little sound, but in your case you will drop a bunch of weight.

 

Ya, that's a bonus too. You don't happen to know which one works?

 

i just checked fs on g35driver.. wasn't that hard there is one for sale for 120 shipped. last post said midpipe was still for sale

I'm sorry, I guess I should have mentioned I'm from Ontario Canada. I've seen them for sale and sold on the forums for 50 - 80 but they seem to sell before I can get my hands on them.

 

mee too! and ye its hard to get them when they are that cheap. where in ontario are you from?

 

I'm from Simcoe, near Brantford (sorta), Delhi, etc. What about you?

 

coupe midpipe will work as well as a Z midpipe with an extension.

 

Ya, I realise that but finding one semi local to me and at a decent price is hard

 

Midpipe doesn't affect the sound all that much. It does, but if you want something noticeable, start with the muffler. Once you change that, then changing the midpipe will have a different tone to it depending on what you do.

 

Some youtube videos have just the midpipe mod with stock muffler and I like it. But, you're right..the muffler is going to come into play soon

 

Try the Magnaflow 10436.


I just installed one a few weeks ago on my 2004.5 and the car sounds the way it should have sounded from the factory. It's not a bolt on, but any reputable muffler shop can make it look right.

Wife friendly, no rattles, nice tone, no rasp and little to no drone.

Save about 30lbs as well.

This one should be up there with the Z-Tube and 5/16 Plenum spacer as must have mods for any 1st gen sedan.

 

Socketz67...that's exactly the response I was looking for!! I really really appreciate your input! I'm going to look into that! Thanks again!!

 

I see that is 2.5 inch inlet and outlet...is that the diameter of our stock exhaust?

 

Yes, just 2.5".

I worried about this at first as well since there are some conflicting posts on the boards regarding this subject, especially in the area where the Y-Pipe transitions into the midpipe. Essentially what the exhaust shop will do is cut out the resonator portion of the stock midpipe, and weld in the new Magnaflow muffler.

Once installed, it looks stock because it tucks up in there under the heat shield nicely, just like the coupe midpipe (I found these much more difficult to find used).

Additionally, I have found a few guys that run this Magnaflow muffler on the G with some success:
That one may exist as a second phase, but for now I am happy with the way the car sounds and performs.
