Cat or no Cat??

[sr20detspec]

i was just wondering if sr20 should have a cat or not let me know what you guys dink??

run the cat. the little power you gain (if any at all) isn't enough to justify 1. getting caught by pigs and the huge fine associated with no cat (or at least in ca, it's 1600). 2. cars pollute enough, the little you'd gain will bite you again later in the butt when your kids have asthma.

but wont it clogged the cat after some time and it might damage the engine?

[SilviaS14KA24DE]

LOL it won't ncessarily damage the engine. You'll loose a bit of pull. Of course the Cat will get clogged over time. Thats why people have to replaces their cats every so often. if anything, put a Hi-flow cat. Or if you only want to do track events (use your car for only those kind of events), then do a test pipe. A test pipe is basically just, well a pipe that goes in instead of your cat.

if youre state doesnt have emissions. ditch it. if it does. keep it. simple as that

Test pipe, but keep your cat around for inspection purposes.

[SilviaS14KA24DE]

yeah, get a bolt on test pipe, and a bolt on cat, so when emissions comes along, you can quickly change it!

[silkk]

get a test pipe off ebay for under $100

hell.. just run open exhaust manifold

i just gutted mine and stuck a 2.75 inch pipe in mine and welded it .. emissions here arent strict .. but still .. looks like i got a cat .. only did it cuz mine was plugged ... makes the car back fire alot tho but after removing it the throttle was alot more responsive

Not having a cat should not make the car backfire more...You will however lost a tiny bit of low end torque (trust me, you won't notice it) but gain a bit of top end power.

Running open headers is a stupid idea, I hope that was a joke.

Hey man, if you're gonna go with a full 3" exhaust then go w/o the cat. If you have emissions or actually want a little bit of torque at the cost of spool time, run a high flow cat, they're only $100

i run a bolt on test pipe track season and the cat the rest. only time i see backfire or flame is when i run the car hard, mostly on track, so it isnt much of an issue
