What do test pipes do and why are they illeagle ? are they similar to a cat. ? searched didnt see a anything to find exact question. Doing exhaust on my gsr wondering what they do.

 

A test pipe is just replacing your cat with more exhaust piping. Not much better than having a high flow cat unless you are running serious boost. Illegal because the car won't pass smog - in most states atleast.

Actually, its illegal in all states, its just that some states don't force you to bring in your car and prove you're legal. California seems to follow a "guilty until proven innocent" mentality when it comes to cars.

+1 for SC haha. No immisions checks here. But yea a test pipe is just a piece of straight piping that replaces the cat. A cat. is the single most lame piece of equipment on a car IMO.

 

eh, just rig a section of pipe to bolt up where the cat is. when you smog it swap the pipe out with the cat.

Tru that.

 

a test pipe is just a straight pipe. It's going to make your car obnoxiously loud, and not always in a good way.
Just get a high flow cat... a test pipe can get you in trouble.

 

i read this went outside to look at the teg i just bought and came to a realization that the guy i bought it from is a jackass. straight pipe from manifold to catback and fart can. thought it sounded like ***.

ive had it 2 days now. going for a highflow cat catback AND OEM MUFFLER this sounds dumb but if you see it in person it looks good "the stock oval tip muffler from a plymoth breeze" lol sounds like a dumb idea but if u see it youll notice it contours to the curve for the exhaust on your bumper almost perfectly ....well it did on my eg dont know about the teg ide have to look.


imma get flamed for that breeze muffler i can feel it

Why are you so worried about being flamed? Do what the expletive you think looks good to YOUR car.

 

not worried just expecting it but thanks for being an open minded person

skunk2 exhaust and test pipe is loud as sin

 

i gained 3 hp across the powerband and 5 ft lbs of torque....test pipe FTW

 

if my test pipe didn't make my car smell, then i would have left it on for daily driving.

 

it smells because it's spewing poison into the air. A daily driver should have a cat. A high flow cat offers almost no restriction. Is 3hp really worth poisoning the air you breath?

TURBO HIPPIE BUG

kinda want a vw bug... one of the OLD ones, you can slap almost any early model porsche engine in them
gotta suck pulling up to the light in a ls turbo....then get beat by a rusted busted turbo 930 porsche powered bug

never mind that was off topic

 

the way I look at it... I drive a Honda. even if I unbolted my entire friggin Exhaust system from the car, and ran right off the header I'd still burn cleaner than my truck (and the millions of other trucks out there) cat or no cat Hondas still burn cleaner than most other cars on the road.

oh yea my truck - 460 big block.

If you have emissions testing in your state, just get a high flow cat. Yes, like what they said above, the test pipe will be loud and not good for the air.

Im from Dallas TX, but the town i go to college in does not check smog at all (college station) inspection here is a joke.

also this has always angered me why is my 1.8L honda put under a microscope in dallas when it gets inspected when a huge 7L diesel engine can blow black smoke and still pass???

Equipment that reduces pollution and makes the world more pleasant to live in while preserving it for generations to come. How lame.

Don't take offense to that. I know that classic cars and diesels pollute more than our little Hondas could if they tried, but I hate that people pull emissions equipment off for a gain of 3-5 hp. At least buy a high flow.

&lt;/rant&gt;
