I have a gutted cat that I throw on for the turbo...but I like to keep my exhaust noise down and it seems to silence it a good amount. My main reason for putting the gutted cat on, is that I've heard running rich will clog your cat. I think this time I might run the cat, but I'm curious how many people here run with or without a cat. I can't imagine the power difference being that much, I'm just curious if anyone has had problems with it clogging b/c of (usually) how rich some honda turbo cars run.

 

Currently running an AutoZone cat. When I bolt up my 3" setup, I have a 3" Hi-Flow Carsound cat that I'll be using.

 

using a carsound hi-flow cat, ~$75 from testpipes.com

That's not a bad price. Was it made for your car or a universal one? For some reason I can't go to that site.

 

I will be using a Carsound 2.5" cat

 

no cat, greddy evo exhuast and its pretty much silent.

 

I got my 3" Carsound cat from ben@importparts.com for $99!

 

Open downpipe here

 

i have 2.5 pipe off turbo straight back to muffler, no nothin in between.

 

i had a carsound highflow cat, bought it from an exhaust shop off ebay for 50 bucks, the place got it to me in 3 days form cali.

but i gutted it on my JRSC prelude.

my hatchback doesn't have a cat, we just extended the downpipe down to meet the 3in thermal.

 

i'm running a 3" carsound cat.

Soon to be installed 3.5" vband downpipe all the way back to a 3.5" Apex'I GT-Spec muffler. I figured since it's not my DD anymore I can afford to go bigger/louder

 

I have a cat, but I won't after this weekend. I think it's starting to get plugged up, so I'm gonna pull it off and throw on an o2 simulator...which should be coming in the mail.

 

I just got a magnaflow cat for 75 bucks (3 inch) I figure its cheep enought to keep a cat on the car

 

Going to a test pipe is worth 10-20 horsepower on a 300 horsepower car. That's a damned good reason by itself.

True but ive hear rumors of not passing emisions (ny does a visual inspection for the cat) and i believe there is a large fine for not having one,

a lot of shops here in pk just check the normal stuff like turn signals, tires and headlights.

ive been pulled over nearly 30 times with a modified exhaust and not one cop has looked under my car (its too low anyway )

btw, where is that sparkly crx?!

 

I purchased an Ebay Test Pipe, and I could actually feel the less restrictive air flow through the pedal.. It did make a noise level increase slightly..

 

Gutted cat. If someone could find me a cat where the core doesn't meltdown on a turbo app, then I'll buy it.

 

Straight pipe that biotch,,,
