Purchasing headers pretty soon and im going with the catted y-pipe but cant really find one and im sure you can make one for cheaper, anybody have any good reviews on a cheap high flow cat?

chirp_fourth

285 rwhp / 314 ft-lbs (75* day, 40% humidity, 100' above sea level, cutout open, basically perfect weather)
276 / 312 ft-lbs (same as above, with cutout closed)

SLP short tube headers & y-pipe w/ a random tech cat
k&n cai
3" cutout after the cat
STOCK tune
cheap custom 3" catback
M6

With tuning I made 297rwhp / 321 ft-lbs w/ the cutout open on the same day.

With a tune and 100 shot I made 386 rwhp / 455 ft-lbs w/ the cutout open pulling 3 degrees of timing.

The high flow cats are at least good to 450rwhp maybe a little more. It didn't seem to choke my setup.

You got the random tech cat, arent those like 200 or so dollars? I was looking for like maybe a 75 dollar one.

And where did you get your cutout, is it electric?

You can get some short 3" cats from Pypesexhaust.com (I think they're under the muffler section) but I don't know if you can get them into a y-pipe without help from a muffler shop. I have the Pacesetter longtubes with their y-pipe and the y-pipe is hitting the driver's floor and comes real close to the torque arm so I don't know if there's enough room to get the driver's side cat in there without some cutting and welding by a shop. Passenger side has plenty of room.

Yea, they are expensive, but work well. I would either forget using a cat, or get one that's PROVEN. The Randomtech is PROVEN, period. Better to spend $200 and get quality than throw away $100 on a piece of crap that chokes your system.

yeah, i have only one cat and its is on the passenger side, so i shouldnt have clearence since you say the passenger side fits well.

So the random tech cats work good for you?

Im having the same prob I need a catted y-pipe for my Pacesetters. Im going to take my Pacesetter ORY and have it cut on each side so I can put on pypes cat. converters on each side and have them flanged in. However on the passenger side the ORY doesnt have enough length to put the cat in before this brace thing so I gotta cut an inch or so off the tubing of the one cat which is no problem. This way I can easily switch from straight pipes to cats just by bolting up the flanges.

Stealth, so you have 2 cats then? I only have one so im thinking ill just have a muffler shop make me a catted y, shouldnt be too hard?

ReD95LT1

Ok I probably wont be able to afford the random tech cats, so what is the best cat for around 80- 100 bucks?

StealthFormula

Your going to need 2 cats because the headers go into the y-pipe which merges into the catback so u gotta get a cat in there after each header unlike stock. You can use one cat however, you could have it welded to the end of the y-pipe and then cut of a few inches of the catback. So basically it would be like halfway down ur car so but it may be real hard to pass the visual inspection. Would be any easy way to do it tho.

Why would i NEED 2 cats if stock, my car has only 1 cat? Kinda confused there, but couldnt i just run headers, to y - pipe, to single cat, to cat back?

Those cats you listed are cheap, how far are you with this process? Do you have the headers ready and just waiting for the cats?

I ordered the pacesetters and soon ill order the cat (s)?

You get what you pay for...save up for the Random tech 2 cat Y pipe. You will be glad you did. I have gone 11.90'S with mine, behind ported heads and a Hot cam. It is a great piece.

Are you going with longtube headers, shorties or midlength? That will determine what type of y-pipe you need. If you go with longtubes then you'd really need 2 cats coming off each header for them to actually work right. A single cat will be too far away from the engine to function properly. If you go with mid-length headers then you can go with a stock type y-pipe.

Im going with long tubes, so then i guess i will need the double cats, is there a fitment problem with the driver side cat, since there is no cat there now?

StealthFormula

Im putting all the crap on tomorrow but i need to buy 2 cats so I can have them flanged in for inspection. So yea u need 2 cats if your going with LT headers.

That does look pretty nice!

What cats do you have on your set up? (flame)

Did you have a muffler shop make the y-pipe?

And what car do you have?
