I have to get my cats replaced, but i'm kinda broke right now. What would happen if i had a straight pipe welded from the header to the "Y" pipe? I'd put the cats back in later for smog of course, but what can I expect to happen? Would the exhaust be louder?

I'm not looking for power gains or a better exhaust note. I just need to get to work :P

If anyone's curious, the cats are clogged as hell and have to go.

 

What kind of headers are on your car? I have a raciing beat header with a straight pipe to the Y, and at idle and cruise its fine, but when you get on the gas at all it gets really loud quick! If you have a stock manifold it wouldnt be as loud.

 

Switching from cats to presilencer was already much louder for me. I would imagine a straight pipe to be tons louder. Would it be easier to weld up ends to a straight pipe and bolt it in instead for easier switching?

 

Stock headers. It'd be stock header straight to "Y" pipe. I talked to the guy and we're working something out. Thanks much for replying.

 

Well, the thing is, I'm just looking at fixing the problem in a lo-cost manner. The cats are clogged and it's making no power. I'm going uphill 20mph tops. So I was just hoping to find a quick solution to get to work for a few more days till I get paid and can afford the cats. I'm not to familiar with switching and all that but i'm curious about for later on.

 

Just take a broomhandle to the inside of the cats. Knock that **** out of there.

 

AMEN BROTHA!!!

 

sorry for the thread jacking but i my precats are clogged i could gut them but how would it be with this setup


replacing pre-cats with 2" piping -- to stock main cat--- to 2.5" piping to a single magnaflow muffler

anyone know how loud this would be? would i have a flame problem? my 5th and 6th are already wired open

 

Daly City? I'm in Hayward. We should kick it sometime.

 

I think your idea will work fine, straight pipe it. And as usual when you see a cop, just coast by. When you have some extra cash throw a bonez high flow cat into the mix. Thats what im doing anyways!

 

Man, I wish I could. I don't think the shop guy will let me do that at his place of business

 

My 88 had gutted cats from the stock Manifold ..all the way back to the Y-pipe..The cat(gutted) had the split air hooked up still and the Ports worked fine..so Yes your MOD will work fine..(and it sounds good!..stock cans on)..the exhaust will smell like Fuel though now..(since you are not "filtering the exhaust"..No catalytic..)

 

IF you put in a straight pipe your going to make more power, it will be louder, and there is no chance in hell that your going to pass emissions

 

I'm 100% sure it wouldn't pass emissions, but for some reason it passed with clogged cats. Go figure.

 

I bought an Eclipse resinator off of ebay for 40 bucks shipped. It helps quite it down.

 

Update: First two cats were clogged massively. Got them switched out for cheap and by not having to replace the main (3rd) cat I cut the cost in half. Car runs like a champ now. Thanks for all the advice everyone!
