Velocity collectors in side pipes ?

[FUNFER2]

What are considered the best velocity collectors for side pipes ?

Brand,shape, steel, stainless ect. And not over the top price. I've seen some of $900 + !

Thanks,

I just bought these, 124 bucks for everything I needed.. I should get them any day in the mail. The 2" primary with the 3" outlet will match up perfectly to my Classic Chambered 3" Cobrapacks. Thanks to RonNichols here for the referral..

They're shaped like a venturi when completed to keep the speed up. Sounds good in theory with the crop of exhaust articles out there, and the price was right compared to SPD or Burns.

Looks well built and the price is fair. Your pipes look great. Did you get the stainless ?
Thanks guys,

Thanks guys,

Yes, but only because Cone Engineering didn't have mild steel at the time of order. I had to get 309 filler rod for mild to stainless, and use SolarFlux B on the backside of the weld area. If I was just modifying mild steel pipes, I would just get mild steel from now on as stainless is a whole nother animal.

It was a good learning lesson though as now I'm playing around with a set in stainless. I'm kinda loosing my interest though until spring, as my kids keep wanting me to take them skiing. Priorities.

I received the Cone Engineering setup today. I assembled the Venturi cones, Mig welded them together and smoothed everything up. The Mig worked well on the cones. I'll use it for for welding the cones to the primaries and "tacking" the rest of the assembly together. After that I'll have all exterior welds Tig welded by a pro.

So far so good.

Hey Ron, Nice work on the collectors!! I'm sorry the MS was not in stock when you called. We try very hard to have everything in stock. And thanks for letting others know about us as well.

No problem Rich, I'm just glad you guys are out there. To think I almost dropped $900 just for merge collectors.... You'll be hearing from me very shortly as I may need another set for my latest project. In stainless too.

coneeng, undy & Ron,

Can you guys supply me with all the parts & numbers for building the side pipes from the collector to exhaust tip ?

I need to get all of it ordered soon but I'm feeling so sick, my brain does not want to function. my buddy Chad said he will weld them up.
Three inch muffler, Venturi cones ect.....

Same size of yours Ron.

Undy, when you have time, please send me all the info with yours and pics if you have them yet.

Goin back to bed.

Thanks,

You got the crud Kevin?

Starting with the turn downs/tips, It's Classic Chambered part# 35-Tip
Then to the 26" bodied, packed muffler, CC part# 3026-COBRA-P
http://www.classicchambered.com/classic/products.html
The last piece is the merge collector kit, 2" primaries w/a 3" outlet Cone Engineering part# CL4-200-3-MS.

You just pitch out the cone, you won't need it. The outlet of the merge collector will be welded directly to your muffler inlet, no room or need at all for the cone. I talked to Cone Eng and this was the recommended way for a 3" ID muffler.
If you're building your J pipes too then you'll want to by their primary alignment tool, CE part# TO-CA4-200200

I already had 2" primary J pipes so I didn't need to build them. I reused them. Are yours 2"?

Instead of ordering the collector kit that includes the transition cone, you can order the parts individually. With the whole kit you get a 10% savings from the individual components but unless you are using the cones you won't be saving money.

Unless you wanted to use them to make some nice votive candle holders for your special lady - remember, Valentines Day is approaching! Actually, wouldn't she love some exhaust components for this special occasion????

FF2,
Are those inside diameters or outside? I'm trying to follow along here as this project interests me. Thanks.

John

[FUNFER2]

All outside. I would really have to make new headers. $$$
But, if it would help out a great deal, I'll suck it up.

[FUNFER2]

Header's- are 2" but, look at the attached photo's. Who ever made these, they squeezed the side's inward, like they put them in a vise ? Was this done for bolt clearance ?

How big of a issue is this ?

J-tubes are 1-3/4"
Collectors are 3"
Muffler housing are 4"
Turn outs are 3"

Are the J-tubes also too small and restrictive ?

Man, it looks like I'll have to spend even more, on new headers, flange,
J-tubes, collectors, mufflers, housing, turn outs,....... the entire exhaust system, before Keiths 482.

Funfer, most collectors are 3.5" OD, so are the exit spouts. I've only built mufflers for one customer that had 3" on both of these. FYI.

Hello Eric,
Since my header primaries are 2", and the J-tubes are only 1.75", I believe I'll make my new J-tubes 2" also.

What company would you recommend buying 3.5" collectors from ?
I assume your mufflers are 3" ? What brand do you like. I'm looking into the 3"
"Cobra Pack" from "Classic Chambered Exhaust". I'll have to decide with or with out packing. I do like to hear the engine,..... a lot.

Below, he mentions butt welding the ends so it's a clean look. I'll do that also.

"3.5" OD to 3" ID Reducer. Trim both ends to fit. Cut at the transition area to fit just inside 3.5" OD collectors, butt-weld the 3" ID end to the muffler inlet. The goal is to smoothly "funnel" exhaust into the COBRAPACK Muffler"

[coneeng]

It all depends on the type of collector you are referring to. A "sweged" collector made from a piece of tubing will be at least 3.5", sometimes as large as 4". This isn't because that is the best flow, it's because you have to start with a big diameter in order to stretch it out to fit 4 x 2" primaries. You will actually find that there are more collectors on the market with outlets that are too large rather than too small.

On a normally aspirated motor we have found a 2" primary flows best with a 3.00" collector outlet and then a 3.50" trasition cone to promote scavenging. When space was an issue we found that it performs better without the transition, staying at 3" than increasing collector outlet to 3.50" immediately. With a turbo or supercharger, then yes, a 3.50" outlet is often called for. With the side pipes we have used a larger collector and skipped the cone if the customer prefers that look.

It is common practice to reshape the tube to fit the port----the trick is to have a hole that is equal to the tube size--ie- perimeter of the hole equal to od circumferance of the tube

[FUNFER2]

Ah,....ok. Thank you. If this does not hurt the flow, then no problem I'm sure but, I'll have to talk with Keith about this.

[Jerry Clayton]

the Ford has a retangular port and the tubes will be resized to fit the header flange.

I am working on specing out 2 sets of stainless headers and the port shape/size to tube size is the big item in the header flanges details.
