Just FYI,

I've found a metal substrate cat that is classified as a performance/high flow cat. Therefore, we will be testing the proven Carsound 93506 (2-1/2"), versus a 2-1/2" Challenger versus this new 2-1/2" metal substrate cat. This testing may be done by the end of next week or hopefully the following.

Hopefully this new cat is everything the sales people say it is.

 

mucho thanks for sharing this with us

 

up

 

Hmm.

 

I should receive the metal substrate cat today or tomorrow. I'll post pictures when it comes in. Then off to be flow tested.

 

make sure you include pricing!

thanks for the great test, btw

 

I will be watching this thread, for I have a JDM Toda header waiting to be bolted up to an ITR.

Thanks

p.s. Dave, I would like to talk to you about purchasing a cat in the very near future.

 

Here are some old pictures of the 2-1/4" (Carsound 93505) and Challenger Cat. These both are 2-1/4" ID cats but everything else (bricks and body) is the same in the 2-1/2" versions that will be tested. I'll get a picture of the metal substrate cat up soon.

Pictures are the same as these anyway.

 

Can't wait for the results. Props to Dave and the guys at SMSP for going the extra mile for us!

 

Dave, if you haven't done the flow test yet...why not test my stock cat? Just for grins, ya know

 

Stock cat was already tested by Comp Tech (I believe) about 4 years ago and I think it was something like 238cfm.

 

this is from a different test...carsound cat tested was part # 94166
http://www.teamspirit.net/rsx/exhaust.html (see bottom of the page) which tested 323 cfm... warpspeed cat tested the best in that particular test
