Finally got a chance to flow some cats for my cat y pipe.
<img src="http://www.quicktimeperformance.com/headers/catshootout.jpg" alt=" - " />
The participants from left to right.
Catco 3"-6907
Carsound 3"-94109
Random Tech 3"-813000
Random Tech 3" 703000
Factory LS1 2000

All where flowed today at JPR at 28" of water. Equal playing fleid. Compare from the numbers today.

Catco-365cfm
Carsound-400cfm
Random 813000-327cfm
Random 703000-535cfm
Factory LS1 Passenger-220cfm
Factory LS1 Driver-251cfm

It was amazing to see how nicely the carsounds flowed. Shocked to see the 813000 Random flow so little.
The metallic Randoms flowed great but for 3-4 times the price of the car sound its not worth it. And the Carsound is less than half the price of the regular Randoms and out flowed it by over 20%

Info for all to see. Hope it was helpful information.

So I will offer the Carsound cats in my Cat Y Pipe and Metallic Randoms by special order. Applications are QTP, Hooker and Jet Hot Headers. The cats are being test fitted in the jig for production. Will be shipping Cat Y pipes in about 2-3 weeks.

Sweeet!! I'm glad that you flow tested the cats instead of just one to put on there. Do you know yet what the price will be for the Y-pipe?

Very cool Barry! Looks like I need some Carsounds when I order your headers! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Barry, you wouldn't happen to have the dimensions (length) of the carsound 94109 would you? Thanks.

Hey Barry why dont you try flowing a straight pipe to see just how much you loose between one of those cats and going with an ORY. I would be interested.

Barry, Great info & decision.

I know your busy and your head may explode from this request but I gotta ask. Is there any chance that the cats can be put on flanges and then swapped out for straights (like FLP) or even, (let me be bold) cutouts. Emmisions frendly to race ready. What do you say Group purchase, packege deal-----emission headers, velocity spike, swappable-Y pipe & cats. Thanks.

Mike K.

Nice research thanks for posting this.

I like your idea with the GP on the whole setup, Blaster. It would be nice to have an introductory GP on the new Y-pipe and maybe a for Header Y-pipe package deal. I know I would need the whole package.

I will have a price next week. Have to see how easy or hard it is to fit in the jig. I hope to be under $500 for the whole y pipe.

Core is 9" long. Overal lenght is 13". 6" wide and 3" tall.

I forgot to flow a staright pipe. I realized that this morning.

Blaster, good news for you. I will be offering optional staight pipes for the cat y pipe, so you can swap. It wont be a 1-2-3 swap but wont be difficult. Price to be determined soon.


Like i have said many, many times before, i will do a speical/gp after i ship out my current orders. Not before so relax. good things comes to those that wait.

No rush for me Barry, I'm just getting excited as the time gets nearer and nearer. I can't wait to make to the call and finally get my set on the way. Thanks for taking the time to do all this for us.

A 3 inch open pipe will flow around 900cfm at 28" h2o.

"Installuni suggests that the stock cats are only good to 258.1hp (flywheel)"

That's about 100 HP BELOW stock? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Wassup Barry? Very interesting tests. I'll be curious to see what the straight pipe flows. Do you think you might could flow a 3" bullet muffler for us as well? I've always wondered just how close to no loss of flow they give.

Thanks! <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

That has to be each. I will flow test stock cats and post numbers when i get a chance. I tested ported heads with 2001 manifolds and cats in place and found one side hurt flow of head by 5 cfm and other side hurt flow 10 cfm over no manifold or converters.

Nope, meant 900 cfm <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> .......I was at the IU test...those hp numbers mean a zero hp loss...so the stock cats support 258hp with a zero loss. 350 engine hp through them may cost 8ish hp...that's why offroad pipes add hp. You can run 900 engine hp through the stock cats....but it might cost you 100ish hp to do it....there's a certain white TTA that runs 9's through a 3 inch catback....but he would run MUCH Quicker without it.

The flow test is some great info, but is flow really everything? I've seen some Catco and Carsound cats break apart in almost no time. RTs hold up great from what I've seen.

Just wondering if longivity was taken into account. Cats should not be a regular wear item, IMO.

thanks for the heads up and the info.
if that flp type system becomes a reality you can put me down for one if i dont go turbo. very nice <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Very cool work Barry...the straight pipe would have been good to see also, although onfire says it does 900cfm..i think he means 9000? Be cool to test that too.

What are the specs on the y-pipe, since I might end up with your QTP headers on the darton 387 all-bore you also took pictures of? A merge collector would be preferable, and I wont be running any cats.
