I got tired of waiting for some company to come out with a descent exhaust for MAXIMUS PRIME, so I said **** it and built my own. Cut the old exhaust off at the flanges(so i could still take it apart if i chose to) and uses 2.5" pipe, dual Flowdaddies, and stainless 4" rolled exhaust tips.

Let me know what you guys think, good, bad, or ugly?
Anyway is fine with me, cause it's mine and I like it.

how does it sound?

 

I like it, way to take initiative! I think I like those round tips, could you take a pic from farther away and at a bit of an angle (like back left or something)? From the pics you posted though, I'm liking it alot.

So did you just replace the rear section?

It sounds mean, do you get any drone though?

 

thanks man. it's just the rear section i wanna get the y pipe from racingline, but if it doesn't come off review soon i'll end up making it too. and it's not really any louder at all in the cab. I mean of coarse a little, but very little. No Drone.

 

Looks great! The 4" round tips were the way to go. I could even see 4 1/2" on there too. I don't want to be nitpicky but is one of them off center? Might just be the angle but they just don't seem at the same center point. Are you going to do a catless Y-Pipe if you do make your own?

 

i think that alot of it is the angle. i was kinda excited once i finished, so i was in a hurry to post pics. it might possibly be a little off center. i didn't measure, i just eye-balled it. but it's pretty damn close. and yes it will be a catless y-pipe.

 

That sure sounded like drone to me. I like the tips pretty much perfect look IMHO!

Nice Job!

 

I think it sounds good as $hit!!! Then again, I don't know what my Stillen sounds like from the rear. I will report back lol

 

Racingline y pipe should be released by end of the month, at least thats what they told me.

 

looks good, looking forward to get mine done here soon..

 

My work computer filters out sites like photobucket so I'll have to look at the pics later. But it's refreshing to hear when somebody doesn't just throw their checkbook at the exhaust shop and say "have at it". There's still hope that traditional approaches to hotrodding haven't died out completely.

P.S. I don't think I've ever had a shop do an exhaust job for me - or bought any of the big-name big-$ kits in a box, for that matter. Y-pipes aren't all that hard to fab up as long as you can get the welding wire all the way down into the "V" without missing or arcing to the tip . . .

So you made the b-pipe too? Everything from the y-back? I wish I knew how to weld, or that you lived closer... Haha

 

No, I haven't made either yet. The exhaust is only the rear rection, but I have entertained the thought of making one big piece. One that starts at the exhaust manifold and goes all the way back to the rear section that I just built. Get rid of all that ****, the cat' and that huge resonator, just one 2.5" pipe all the way to the Y. Then again this is my wife's car, not like we'll ever really have a "track day" in it. So I may just slap some cool wheels on it and call it finished.

 

Won't you run into o2 sensor issues if you start yanking out the cats? I heard the newer cars can be rather finicky with that ****. Back in the good old days we could run straight pipes start from the manifold, but not anymore.

 

Back to the exhaust sound for a moment - I don't really hear anything unexpected. Lightly muffled 6 cylinder engines have a characteristic sound that you can't get too far away from almost no matter what you do, and you can't really tell 'drone' until you put the engine under load at speed.


Norm

 

Mrein769, probably a good 90% of the time you're right. B/c most cars monitor exhaust gases before the cat' and after. The Maxima is no different there, but the Maxima has 3 cats', one attached to each exhaust manifold and one downstream. The cat' that I would be eliminating (the downstrem one) is completely unmonitored. So the ECM would never know it was missing.

 

Oh ok thats cool. Just making sure you didn't do all that work just to have about 20 different codes flashing in your face.

 

That's why I love this forum, ppl always trying to look out for one another and help. I mean of coarse we have a "hater" every now and then, but for the most part everyone gets along pretty well.

And before I forget, thanks alot for all the comments and input guys. I really appreciate it.

 

hows it sound? Were you not interested in the new Stillen exhaust?

 

Check at the bottom of the OP's first post for a sound clip.

 

If you don't mind me asking, how much did this cost you? Do you (or your wife) notice any added power? I really love the look of those round tips.

 

finally!!! someone did a custom exhaust great job!, sounds mean to me, would love to hear more sound clips

 

what is the stock exhaust size?

correct me if im assuming incorrectly but , by "flow daddies" you mean flowmaster? if so which particular ones did you use..

i do like the sound btw, good job!

 

Flowmasters were about $80/ea., stainless tips $70/ea., then i had to get the pipe and have it bent i think it was like $315 all together. Can't really tell a difference in power, but it would have to be pretty considerable to feel it in the "butt dyno."

Oh yeah, I used 40 series Flowmasters. Their website had alot of info. about all their mufflers. I did my research and got the loudest one I could, without having to hear it inside the car.

 

Yeah it sucks that trying to dyno a CVT doesn't really show the results of mods, so I've been told. I could be wrong though!!

Supposedly the only way to get actual numbers to show gains or what your mods are doing is to remove the engine and dyno it separately from the CVT.

My thinking is that someone with mods should put their car on a Dyno before and after and see what they come up with.

 

1) can you tell us what you mean by "then i had to get the pipe and have it bent"? I thought I read where you just put on the Flowmasters and tips.
2) What part number are the Flowmasters? I couldn't figure out which one from their website.

thanks. (sorry if I missed something obvious)

 

I cut the rear section off a little past the flanges. So I deleted the little resonators in front of the stock mufflers too. After that I had about a 3' section of pipe on each side missing. So I got some pipe and had it bent so I could mount the mufflers straight.
So, in not so many words, I built a rear section exhaust.

Not positive about the part# but i think it was 952545(center inlet and center outlet 2.5") or 842440(center inlet and center outlet 2.25").

 

Ole Maxima sounds dang good w/the Flowmasters! Never would've thought it; great job man!

 

had to search to find this thread bc this is still the sickest maxima ive ever heard. 10xbetter than stillen and hardly anyone else offers a catback worth a ****. nice job bro ill be doing this soon to mine too

 

Not a bad job..I thought of just going with the Y-pipe and deleteing that resinator in the mide pipe and leaving the stock cans.Looking for that G or FX sound.But I ordered the BORLA but still need to wait another week for it to arrive.
