Apex'i N1 exhaust sounds like crap?

[NskGenakuDuckie]

Ok here's the story.... I originally bought the apex'i N1 muffler back in 2001 and had a 3" custom piping made for it. The car only had bov, intake, exhaust; and it sounded GREAT. Partial throttle acceleration from 1st to 2nd and 2nd to 3rd sounds like a supra from the interior. From the outside it had a similar exhaust note to the subaru wrx's.

And then.... I had it off for almost a year after i got my fix it ticket. It sat out in my backyard until just recently when I put it back on along with the megan racing 3" downpipe. I also added a 50 trim, 650's, 255 pump, maft/gm mas setup, fmic etc etc.... and I was expecting the car to sound even better.

To my surprise it sounds HORRIBLE.... sounds like an n/a eclipse. I told my friend about this and he said it could possibly be because I dropped it (my dad did when moving it from garage to backyard). So is it true that dropping the muffler can make it sound different? I know this is no big deal but the nasty ass exhaust note is driving me nuts. I hate driving the car now. You guys have any opinions on this?

Did it get rusted out? I really don't think any of your mods would change the sound (that much anyway) but if it is rusted out then it would change the sound.

check it for any cracks or leaks yet?

 

[blcknspo0ln]

i'd have to say it's leaking somewhere

mabey put a bend in the pipe or.. when you did your down pipe if you didnt put a cat in and replaced it with a test pipe the issue may be that you have a section of strait pipe that the exh is resionateing in causeing it to sound like crap.

the stock down pipe has a slight bend to it then goes into the cat hence no resination.


just a idea, hey ive had it happen

Mine sounds sweet, but I have a 1g and the apexi N1 muffler looks like a big ass ricer trash can hanging down from the back of my car.

It is coming off for damn sure and getting replaced with something else.

Love the pipes though...good welds.

Wow I didn't get an email notice, had no idea I had so many replies.

To answer some of your questions.... yes it is most likely rusted. I had it wrapped up in a plastic bag, but not that good though, I'm sure plenty of moisture, dirt, bugs have gotten into the muffler for the 1 year it's been sitting out there. I'm sure there are no leaks.

This is frustrating because it doesn't really affect performance, but the car is just annoying to drive. It sounds like a riced out honda for christ sake. When I let off the throttle at lower rpms I would hear a spoon knocking in a tin can noise.

And to clear things up I didn't have a cat before when I only had stock dp, intake, bov. And I don't have a cat now.

muffler packing in the muffler may be damaged from rain or whatnot?

 

[Attack Eagle]

that would be my guess, no packing or very little left so no sound absorbtion of the upper frequencies leading to a sound like a couple of pissed off yellowjackets in a coke can... I mean like a honda

I fixed the pre-turbo exhaust leak, ported out O2 and some of the exhaust manifold.... now it sounds better, but still far from sounding "good". After dyno tuning lets see if it'll sound better.
