Exhaust Questions
 

Ok im in the process of buying the last of my exhaust parts. I was looking at the magnaflow high flow cat off ebay. iIm looking for the exhaust to be done for the meet on the 13th CT meet so if you guys could help me with some answers to some questions i would appreciate the help.

1.How long of a cat should i get? (I saw 13" and 16" magnaflow cats on ebay)

2.If i get the o2 bung for the cat does they exhaust place put it on for me including the flanges?(just wondering)

3.When I get the exhaust done should i replace the sensors at the same time or leave them till they die?(70K on the car)

They are not CATS, it's pretty much just a mid pipe with a non functional honey comb. Don't waste your money on it.

Do you have headers?

no headers just stone racing y pipe i bought off ebay and a magnaflow muffler i bought from a friend so far and i wanna get a b pipe from LLS Exhaust

Looks like a cat to me... cheap to. Or is it?

What do you think Dave?

I had that one from WARPSPEED. It lasted 2 weeks and the inside fell apart, twice. That's a pretty good cat but like I said, mine fell apart. Don't know why it happened, maybe cause of the y-pipe, maybe I was running rich. Whatever it was, the thing fell apart rather quickly.

I figured if the cat is to loud or it just sucks ill throw the stock cat back on i guess. IDK its 50 bucks i figure if it sucks im out 50 bucks which isnt that bad..Any body else have this problem with there high flow after market cat guts falling apart?

It was the carsound cat from warpspeed.

just curious where did you buy it from? ebay?

It is only $50, but add shipping, welding on flanges, and the install. Plus $10-20 to put a O2 bung in the b-pipe, can't really put it in the cat. You're looking at $100 easily. Got it from warpspeed, called them and ordered it.

so you think i should just keep stock on im guessing ive heard there is like no power gains from high flow cats is this true ? so i figured it would only change the sound of it. What is your set up dave?

It won't give hp or change the sound. I have a custom intake, Budget y-pipe, stock cat, and a APEXI WS cat-back.
