So finally i installed the coupe midpipe in my sedan and its rather disappointing. First off, anyone considering this mod, don't have high expectations. No one mentioned it causes clearance issues with the heat shield and the metal bracket that look like a mini upside down strut bar. I had to remove both. After finally fixing the clearance issues, I started it up and reved a couple of times and it sounded a tad deeper between 1000 to 3000 rpm, but everywhere else in the power band is the same as stock. Also not sure if it feels quicker or gained any horsepower... I highly doubt it.....

 

What have you been reading?

There has never been a claim of POWER, all a mid pipe does is add a different growl and shave some off maybe 5lbs. Because it replaced the larger resonator on the sedan with a smaller one off a coupe. The pipe isn't larger, so no gains should be seen.

 

made my car deeper also but it one of the best sound mods you can do for cheap. best 60 bucks I spent!

 

Sorry you're disappointed. I had this mod done and it's the best thing I've ever done.

 

The '04 resonator could serve as a boat anchor, so you shaved 20-30 lbs. The resonator went from 30" of baffles and perforations that reduce sound, to a 9" tube which adds a growl to your setup. Maybe unplug your negative battery cable for a while (15-20 minutes) and plug it back in. Once the ecu rests you will notice a bigger change, basically it needs to adapt (100-150 miles) to the new exhaust flow

 

Interesting, I will try a ecu reset and see what happens. Thanks.

 

lol seriously? when you took off that sedan midpipe did you notice how much it weighed? i felt the difference in addition to the sound

 

I definitely noticed the sound difference when I first put the coupe (Z actually) middy into my stock exhaust system.

 

lol yes, that thing was insanely heavy.. I think it must have weighed 50 pounds easy... well, on the bright side the car weighs less ...

 

yea i couldn't break my tires loose in manual mode with the sedan midpipe on but could after i replaced it i noticed..but then again i also pulled off my y-pipe and muffler as well

 

I'm thinking doing the swap on my 03 but I'm worried it will make the sound level inside the car annoying. How loud does it gets inside the car? Is it louder on the highway?

 

its a decent growl added.

I can see how some can say its annoying and some can just love it. My currently set is listed below and some days, i like it and some days i wish it would just be silence.

 

to me, its only noticeable in low RPM. One of my favorite mods yet.

 

So you removed the heat shield and mini strut bar thing. Do we not need these pieces? I want to do this mod but I heard about the clearance issues how much of a problem do you think this poses for newbies?

 

It won't be annoying and if you don't like it, it's cheap and usually easy to sell. Go for it.
