Coupe Midpipe Question

[k@osx71]

Not sure if this was covered before, but I did a search and couldn't find anything (Not sure if I should've search even harder like some suggests) but would a '03 coupe midpipe fit on the '04 sedan?

Absolutely. I have one on my car and love the sound. It also ways about 25-30bls less than the sedan midpipe. So you can kill two birds with one stone. Better sound and less weight, FTMFW.

yes. I have a 03 sedan and did this mod, but the 04 and 03 use the same mid-pipe.

At low RPM (around 1500) under light load, you actually get a strong bass note that can be a little annoying(seem to hit that a lot when cruising). As you gain revs, the note cleans out and sounds better, as you hit 4+ under load, you get quite a nice bark! Over all I like the mod, especially for the price ($90 shipped off ebay). I talked to a tech at stillen and he claimed 10 HP. Not sure if it did that but I wouldn't be surprised when you look at the stock sedan baffling section, that has to be super restrictive.

i also want to get the coupe midpipe for my 04 sedan.. what are all my options for upgrading my exhaust? do some kits come with a new midpipe?

[g35sedanlover]

Anything "cat-back" will have a new mid-pipe. I believe that the OEM coupe mid-pipe is the only one that you can use by its self. The rest will come as part of a cat-back kit. Other options are Stillen (generation 1 and 2), borla and tanabe to name a few. Stillen gen 1 seems to give the most HP but will cost a solid grand. Gen 1 is fairly loud (at least when you rev it), gen 2 is quieter with close to the same power. Both are actually dual exhaust that runs through the same muffler. I haven't seen specs on the Borla or tanabe but I am GUESSING both will be a little behind the stillen.

so the stillen kit with have a new Y pipe and everything?so whats better for performance? to piece it out, getting the coupe midpipe, a new Y pipe and whatever else there is.. or getting the stillen kit?

none will have that tone that is rair to other motors that the VQ's give us... I love it and you will be happy for the 100 bux it might cost you.

Get the Stillen kit. Not only will you replace your mid pipe, but you'll also replace the restrictive OEM muffler.

Do it!!

when I called stillen, they said the mid-pipe upgrade was good for about 10 HP. The generation 1 stillen cat-back claims about 22 HP.

Were you pretty happy with the coupe mid-pipe addition?

[g35sedanlover]

yeah, can't beat it for the price. It sounds great at start up and WOT. When you are cruising and under light throttle around 1500rpm, you get a strong bass note that I am not a huge fan of though. Overall I am happy with it.
