Has anyone used a different hi-flo cat besides RT? What were the results?

 

I believe there is a Carsound cat and another brand. Both have to be weld on or you need to weld on flanges. Not worth the trouble so just get RT. If you don't have emission testing. Just gut the cat or put a straight pipe on.

 

I'm ordering a Carsound cat from Warpspeed and they are welding flanges on it so it will bolt up to my car when I get it. The price is much better than RT too.

 

Really? How much better was the price? I just ordered my RT cat 2 hours ago on a http://www.groupbuycenter.com order for $159+ tax

 

do what i did cheapest way by far keep or get a used cat and just hollow it out then u have a strait pipe then when u go to emissions change to the stock cat and thats it then just switch back to hollowed out cat.

 

what does "hollow it out" consist of? how hard is that? and what does a used cat cost? thanks!

 

We have found a new supplier for our Cats. The good news is we are dropping prices by $15, now at $110 + shipping. See our web page, it will be changed later tonight. WarpSpeed is constantly trying to bring quality products at competitive prices. See my post on Gen Max site also. Dan WarpSpeedPerformance.

 

the random technologies hi-flo cat is such a good mod, over any other catalytic converter out there. i was looking at the dynojet graphs on their site, and it was really impressive. IMHO don't settle for less than the best.

 

We also checked out the Random tech catalytic converter, in fact we bought one. We dynoed it against the Carsound and realized a mere 1hp and 2-3 lbs of torque difference. The Random IMHO looks just like a Catco brand catalytic converter only with one less heat shield. If the Random did better I would have one on my Jeep and Corvette, I know Dan would put one back on his Maxima. We still use the Carsounds on everything we drive because they are the best value for both price and performance we have found.

We have been flow testing several brands of cats, the method we use is comparing the flow of a straight pipe of equal length and diameter (using a Flowmeter of course, about $4500.00)to a cat of the same length and diameter, once again we have not been impressed. I am just not sure they are worth the extra cash for the minimal difference we have seen.

We were also comparing several of our mufflers against the legendary FlowMaster, the results showed the Flowmaster had 7% less flow than our muffler of similar length and I/O size. The Flowmaster did come with some real neat decals though.

i actually canceled my order with them to weigh options

found a replacement. then canceled the groupbuycenter deal to weigh options

 

Am I looking at it wrong, or on your website did you do a dyno comparison between a setup w/ 2.5" carsound and a 2.25" RT cat?
Your pipes/cats/exhaust/etc all advertise 2.5" piping. In that case wouldn't the 2.25" RT cat be at a disadvantage because of the restricted flow? (even though your site says it still outperforms carsound by 1hp/2-3ft-lb)

Any help appreciated, as I'm looking into a complete intake/exhaust setup, and I'd love to buy from one vendor.

 

Doesn't the RT cat only come in 2.5 and 3 inch? So the 2.25 sounds unreal.

 

that's a very expensive flowmeter Dan

 

FYI it was a 2.5" Cat. Had her bolted up to my complete WarpSpeed system. When we dynod, it was a fair test. The only component we switched was the Cat. In my honenst opinion switching cats won't make a big difference. People who say they have felt big h/p gains are probably overstating or justifying spending the extra $50 + for the RT cat. If I had a 4th Gen. I would buy our WarpSpeed Y-pipe, 2.5 Carsound cat and then see how the rest of my system performs. It's going to be louder from the increased flow. I would then decide from there if I wanted to replace my b-pipe and Muffler. WarpSpeed does not offer a b-pipe because there are several on the market that have good prices. Courtesy Nissan offers one as does Stillen, I would probably goe with Courtesy, Kaleb is a very decent guy and I know him personally. I haven't heard very nice things about customer service at Stillen, but have no personal experience. Hope this clears up this issue. Remember just because you spent more money does not always mean you got the best Cat. Our driving force has been to offer quality products at bargin prices, not spend alot on advertising,then back it up with qualiy service. Dan WSP

 

I only mentioned the cost of the flow test machine because it seemed an important fact for the company who was testing the mufflers and cats with me.

We have been using the Carsound because they have personally worked on our vehicles, they are affordable and are of a quality equal to that of the Random. The test we have performed have not shown a dramatic difference between the 2 converters. I just figure it may not justify the extra expense. If there was a dramatic difference I think we would try to sell them as well, or at least keep looking for another less expensive alternative.

Can you comment on the size of the piping 2.5" vs 2.25"?
I've read several posts regarding the possible difficulties of routing 2.5" piping under a 4th gen. As well as that 2.25" offers about as much power as 2.5". Will WSP have a 2.25" setup available?
Re B-pipes: If WSP produced them, a customer could buy a complete engine-aft setup from WSP. Single shipping cost and known setup config. It would certainly sway my decision in buying product. I'd rather get the complete, known to match/work setup from a single source, even at a premium of $$ or slight loss power (not that you're products mean that compromise).

If I'm trying to keep the noise down while increasing flow, what effect does a resonator play here, noise vs flow?

any help appreciated

 

I appreciate what you Warpspeed guys are doing even though I don't own any of your products yet. Cost is always an issue to me. It's good to see competition to the big names out there.
