: Best high-flow cat. convertor for the Classic Se-r? Peanuthead 01-19-2002, 06:03 PM Well as the title says, I'm looking to find out what the best cat. is for the classic se-r? I know the random tech. is pretty good, but it is like $180. I thought about catco, but I can't seem to find any online prices for them. PNWser 01-19-2002, 06:39 PM What do you need it for? Need it to pass smog? or just trying to get rid of a restriction (which the cat really is not that much of a restriction unless you boost or squeeze a whole bunch, or if it is toast) get a cheap cat if it is for smog, and a test pipe for afterwards. The cost of replacing the gaskets will be much cheaper than getting a spendy hi-flo cat.... david lau seralex 01-19-2002, 06:50 PM here in l.a i gotten prices for $130 for a catco installed.high flow cats really don't make a big difference like some people think 12 to 14hp. if your willing to spend that kind of money buy a cam or a cai chriscar 01-19-2002, 06:53 PM Originally posted by Peanuthead Well as the title says, I'm looking to find out what the best cat. is for the classic se-r?

You want a 12" long 2 1/2" cat, Summit's part number is CTO-6806. Put that number in the "Enter Your Summit Part Number" box, to search for it. Chris Peanuthead 01-20-2002, 08:06 AM The reason that I inquired about a high flow cat. is because I thought I would need one if I got an header and exhaust setup to take real advantage of the power. PNWser 01-20-2002, 04:43 PM Do your homework before you spend your money...!!! The stock cat flows well if it is in good condition. You should be able to tell if it is good or not when you have the secondary off the stock manifold off during your header install... later david lau silversx 01-20-2002, 05:02 PM woohoo! i just got a catco for $60 shipped! it was the last one, too. anyone know anything about the catco's? Stiletto 01-20-2002, 05:07 PM they're cheaper than Random Tech cats!! :D :D Laly 10-19-2002, 11:28 PM well i will be installin a HS header next week. i have a courtesy exhause with a magnaflow muffler. 2.5" my converter is bad. should i just get a stock one then since you guys say that it is pretty good. Has anybody used a magnaflow cat converter? what are you guys using with your HS headers? Peanuthead 10-20-2002, 04:27 AM I know that this post is old, but I'll reply to it anyways. :) Is it your cat. or muffler bad? I couldn't quit tell exactly which one it was in your post. If you need a cat, I have a 2.25" Catco with flanges that you can get. They are both brand new and never been used. cewyattjr 10-20-2002, 08:29 AM At what amount of mileage does it make sense to switch out the cat? Just picked up a '93 SE-R with 107k on the engine. The outside of the cat looks pretty dark and crusty -- maybe time for a new one? :confused: Peanuthead 10-20-2002, 09:01 AM The only way to really tell is to take the cat. off and look through it. If you can see light at the other end pretty easily then you should be fine. The light should look like someone is holding a flashlight off in the distance to the cat.

Racerlinn 01-21-2003, 11:01 PM These are both the universal versions that require flanges to be welded on. Try a search at www.summitracing.com | ||
