Man, can't wait to here next vid. I love the way that sounds. What kind of magnaflow are you running?

Somehow I managed to figure out he is referring to an Equal Length Y-Pipe.

as shown, yes. but i didn't feel like spending all friggin night making the diagram perfect. it would be narrower in real life.. and the bends would be smoother too. that's just for the general idea of how it would be.. i just didn't have anything to make non-circular bends with on powerpoint.

The bend that I made has the tightest radius possible which is best for ground clearance. My front end is very low and anything lower to the ground will hit. A larger radius bend is probably only worth 1-2 hp.

Like DanNY said, It will hit on the engine mount and/or x-member. This design is very similar to the ELYP's made for the VQ30. I know you said that's it'll be different, but I just don't under stand how it's possible. You'll have to show us when it's done.

Those donut bends are supposively the tightest bends you can buy. Probably why he mentions them. I've researched them for my turbo crap

Not tighter than I can make.

Youre not far off the original stillen design for the 4th gen:


I really wanted to mod my WSP, Im sick of the drone. Thankfully OBX just came out with equal y headers for the VQ. You guys are SOL for equals, so call up Cattman or WSP to get these mass produced!

that's an idea... the junction being vertical instead of horizontal... but you're right that is fairly similar to what i was gong for. just without the upstream 02 sensors. and a slightly more relaxed bend

lol, most of the "masses" in here won't pony up $$ for a proper tune up, much less a warpspeed y-pipe..

The only problem is mass production requires mass demand. I can't see Brian Cattman being interested in producing these. WSP might, but I doubt it. Maybe if they get deposits from people. :shrug:

Before you brought these up, I was just looking at the VQ OBX ELH's. They look pretty nice!

I really like the stillen design and I thought about making my Y-pipe a little more like it, but it would have been more cutting and welding.

Does anybody know if a vg manifold will bolt up to a ve? I know the vg exhaust ports are round and the ve exhaust ports are oval, I just would like to know what else is different about the flanges. For some time, I've been thinking about trying to make the vg obx headers fit my ve. I don't think the vq headers would work on a ve because the motor mounts are in a different location.

idk understand what is the performance benefit to an equal length y-pipe it seems like more resriction and more turbulence for the sake of sound, a nice sound, but still i smell rice

shut up w/ your rice crap. takes one to know one anyhow... this dude did something good here (also idk understand = "i don't know understand".... )

equal length exhaust matters because if you have different-length pipes, then the exhaust pulses will hit each other instead of coming down the pipe at even intervals. if 2 exhaust pulses hit each other, you add resistance. then there's a space where there are no pulses, which is time wasted.

same reason performance vehicles have crazy headers like this.. so the pulses come out evenly

(these are for a vq35)


for a mustang

i was waiting for someone to say that....but how the heck do u know all that stuff? did u get training from some master technician or its ur personal experience..?......the red part is 100% right and plus they make equal length to match the frequency with their designed muffler...not if u put after market muffler and cuz then frequency changes and tone of muff changes too and then it directly effects the back pressure to go up and down...

and as far i can tell by the design of 505max94se...he probably have gained a lil low end...

edit: did u check how many lbs of back pressure u have now 505max94se?

well, i really didn't mean to sound like a downer. you've come up with something new, and you have noticed an improvement. nobody expects the first attempt to be PERFECT and you should be proud of what you did. but like any prototype design, a few tweaks will usually make it even better. and don't mind burhan.. he's learning...... i think.

Of course. I just wish more people on this board realized this and weren't so harsh on everybody that wants to do something new or different. I understand how to accept criticism. I just get frustrated with how the majority of the 3rd gen board is so negative.

Dude did i say sumthing wrong? I was jus replying to cape? I think u have a gud design and if i said sumthing which might hurt u den i apologize for dat and cape didnt sounds like a downer either he was jus explaining how can we make better exhaust

Actually I was welding a little more like Jeffy

Your exhaust is now on Jon94se's Maxima.

Did you try turning the wire-speed down? to the lowest setting? or if it's like mine- until the wire will jam up if you don't have the ?liner/cord/gun? perfectly straight.

I don't really see how it could be restrictive at all. Long as you got mandrel bend on that 180 degree you should be alright.

honestly...do you care what others say? you're driving your car every day...so why do you care? YOU like it...who cares what others say.

it's new...people will be a little negative about it. personally i'm not a fan...but can't say that it's not a good attempt....so i didn't comment except for the welds.
