Default Pics(inside) of Random Tech #703000 3" Cats

Well, they sure aren't much to look at. lol

These are the cats to have if you want high flow(560cfm) and don't have much space to work with. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

Do they make those in 2.5" and if they do, would you happen to have the part #.

Sorry, I don't know. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

Here is there website. I don't think anything is listed about these converters though because they are relatively new. I'm sure they know. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Ummm.....just a little. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

BTW, Carol at Tbyrne gave me a very good deal on these bad boys considering what the retail price is. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

The reason I went with these is because I am going to run a full exhaust all the time and wanted some high flowing cats that were very short. I don't have a lot of room to run a cat or cutout the way I want to route the exhaust.

The exhaust will consist of AS&M 1 3/4" headers(for a truck) with modified 3.5" collectors, 3" cats(couldn't find a 3.5"), 3.5" pipes to a 3.5"->4" flowmaster y-collector, finished up with a 4" magnaflow race muffler with a turndown. It should flow relatively well behind the 422. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

So if there were a 2.5" cat, which I don't know (but wish I'dve bought instead of my 8100 series bullets <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> ) it would likely be part # 702500.

I'd contact RT and find out. They were surprisingly responsive when I emailed them about a different question. I had an answer in less than 24 hours!

Originally I planned on installing a single one of these at the end of the y. Given this converters flow rate, will a single one in this location create a substantial bottle neck? Also does anyone know what a 3" pipe flows at 28" ?

Thanks

A single RT would be too big of a restriction. A 3" single open pipe flows around 940cfm at 28"

Yes, the part# for the 2.5" in/out is 702500. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

These cats are made with a metallic substrate, like Euro/Japan cats... Won't meltdown like USA ceramic substrate cats...

I bought a pair <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> $221 each.. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />

I've installed one in my Mufflex drivers side downpipe already & still have RASP, on this side. <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" /> It's only half as bad as before.. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> I'm thinking that the high flow rate has something to do with RASP...
