tell ronnie i said hi.
he used to be in NY and then decided to pack up and leave.

he's good but expensive (at least when he was in NY).
also he can not make a mandrel bend THAT tight. there's a min radius that he can make. outside of that the machine won't do it. the mandrel won't ever come back out b/c it'll be stuck in there.

yes he's a big import guy.

 

That's really cool that you know of him! We chatted for a long time while he was making my custom equal length Ypipe. He told me he's really thinking about going home to NY one day.

 

just cuz they have a bender doesn't mean it's a mandrel bender. alot of places with benders are just compression benders, which don't maintain the inside diameter of the pipes like a mandrel bender does. trust me, it matters.

 

yeah he's definitely a good guy. not sure why he moved to NC. just one day i went by the shop and the guys said he up and moved, packed up the bender and left.

he wouldn't let me touch his tubing beader..LOL...but i have my own now.

good to see he finally got the Z up and running. it was under a cover in the shop for a while.

 

check when they make the bend...does the machine pushes a tube looking device inside the pipe before the bend is made? if not then it's not a mandrel bend.

 

Tired of the cold / traffic /taxes / e.t.c. Like most! I just did something about it . Winters are short and mild track is open as long as its 50 degrees . Still alive and well. Still miss that n.y. food cheers bra www.rjscustompiping.com

 

Expensive that depends who you compare me to shea stadium yes I charge more . Over here in n.c. also that depends who you compare me to henrys/ bobs/ jerrys /harrys etc These are local muffler shops that people here go to. Which in my opinion charge pretty close to what I charge for mandrel bent exhaust work. But people who know the differencemost of the time end up at my shop . Still the same quality work

good to see you on here. people complain about the price...but IMO you were the only game in town that did what you did so i didn't have any issues..besides kooks but they are farther out on LI. i still came by and bought tons of mandrel bends.

the shea guys used thinner gauge pipes but like everything else you get what you pay for.

 

My equal length Y-pipe is done!







I've got about a finger's clearance between the oil pan and the rear pipe:


I got the secondary pipes lengths about 2" away from being totally equal. (Previously they were different in length by about 22" from cylinder head to "Y" -- so I removed 90% of the length difference.) As you can see from my design, I did this by both lengthening the rear pipe as well as shortening the front pipe.

Result: in terms of quieting the exhaust (the main reason I did this) the results were mixed, althoughgenerally positive. The exhaust tone is markedly different now and does sound much better. I would describe it as more mellow and refined sounding. Sounds more like a performance tuned BMW inline six. Before, it just used to sound like a car that needed a muffler (and for the record the rest of the exhaust is a full WSP 2.5" mandrel bent, with resonator and a stock cat, and I've tried three different mufflers on it.) The tone "mellowed out" a bit, which is good, but it still is pretty loud in some cases.

In terms of change in power and torque, I don't think it made much affect in the low RPMS, but I was real surprised how it seems to now just keep pulling harder and harder as the RPMs rise, especially in the 3500-redline (5500 RPM) range. I would say the butt-dyno is registering a definite increase in power here folks.

 

Here are some other pictures of it:

Ground clearance shot: (ELYP is about as low as engine support; Swaybar is lowest)


Modified front pipe (it's close to the oil pan now)

Got any Vid of how it sounds?

 

Ok i see where ur coming from with that the inside diameter can get smaller if the just bend it thanks for the heads up on that one.

I will see if it does so it will put something inside to pipe to make it hold its inner shape?

 

Welcome to Maxima.org Ron! How did you find this thread?

Here are some shots of the custom mandrel bent Ypipe Ron at RJ's Custom Piping made for me. It was a TIGHT fit trying to get the headers that were made for the 3.5 Altima to work. The VQ35 engine is a lot bigger than the VE30. And since the Ypipe and crossmember location is switch, it made things even more cramped!

Thanks for your help Ron!

 

Good job!

 

With my Y-pipe modification, I raised the position of the pipe over the swaybar by about 1/4", to add space between Y-pipe and swaybar necessary to remove some cheesy swaybar spacers I had in there previously to keep the (WSP) Y-pipe from banging on the (Suspension Techniques) swaybar under hard acceleration.

However, this change did throw off the alignment of the rest of the exhaust system, which I think I should fix before recording vids of the sound. (Right now the resonator or is pressed up against a heatshield under the car, and is probably transmitting engine vibrations to the chassis.)

 

Kooks is top notch . But is crazy expensive!

 

Glad to see some old frendly faces . Dan btw do the search. No muffler shop in the state of n.c. does mandrel bending.Did my homework

 

HA!...then you're good to go.
you think you're going to start selling online anytime soon or is it not worth your time?

 

that looks pretty damn good. another excellent job by RJ's.

I finished aligning my WSP exhaust system with my new Y-pipe. To get the resonator aligned well in the tunnel, I had to make a cut and a weld just ahead of the resonator. I also found and added a perfect fitting gasket to the flanged exhaust pipe connection that is just beside the fuel tank. It was previously just metal on metal connection. I feel adding it may have helped quiet the exhaust noise additionally.

For a VG, it's sounding pretty good now (at least when the engine doesn't miss, which does happen more often than I'd like at idle, due to corroded injector electrical connectors.) I'll have to record a vid for you guys soon.

 

doo eet! i'm interested to hear how the EYLP sounds on a VG vs 505's VE.

 

dam that sounds nice.

 

After a few weeks of driving around now with the ELYP, I came to the following conclusion: although the equal length mod may have made the exhaust tone sound "better" (more refined, etc), it did not really make it any quieter. My exhaust remained loud and boomy. Loud enough to set off car alarms going up a certain parking garage ramp. Just like it did with the unequal length Y pipe.

But... I did figure out how to solve my loud boominess problem! It just wasn't the equal length Y-pipe. I detailed it in a new thread here (since it's not really related to an ELYP):
Longer exhaust tip effective in quieting WSP+magnaflow exhaust

 

i'm after the same thing... not quieting it down but for the sound!!!!!i want it to sound like a vq35de and this is exactly the way to do it!!!!! i'm also really happy to hear you got more top end out of it from the original unequal y pipe design, which is what i'm after as well... i don't need more torque, the fact its 3 liters and v6 is good enough. i want something to compliment my 00vi and 7200rpm redline!

your welds are soooo pretty too. they remind me oh hand crafted expansion pipe exhaust on 2 strokes (http://www.ansaracing.co.uk/WebRoot/...ne-2t_copy.jpg) i'd really like an equal y pipe... is it possible you can get one made for me? i got an SS304 WS available to trade/for sale if you do!

 

Good luck but I don't think the VQ30 will ever sound like a VQ35 it's got a slightly different growl!
