2 1/2 0r 3 1/2
 

Hey gots myself a problem. I Want to know If I put 3 1/2 in pipes on my exhaust will it lose a lot of torque? AND SOUND GOOD. or should the 2 1/2 do me just fine?

you will lose power... DO NOT DO

the exhaust won't flow well at all... if you think about it... the gasses will actually tumble from all the extra volumein the pipes...

so 2 1/2 will suffice

Yep don't go bigger than 2 1/2.

if your still stockish i would say even 2 1/4

Really so it wouldnt make it any louder?

i guess it might, but it will run like ****.

If you want to be loud just pull the cats and get a loud muffler.

I dont think thats legal in Cali

oh yea. . .

i swear if ihad to live in Cali i'd kill myself

yeah CARB sucks out here

Yeah I've heard that you really only need like one inch diameter per 50 horsepower or something like that, 3.5 inch exhaust wouldn't do any good, only bad.

well i did get the idea from a mag article and the guy had over 1000hp
owell 2 1/2 is better than stock.

hey but would it be worth the money for me to get higher flow cats when i buy my exhaust? will that make it louder?

high flow cats are supposed to be louder than the stock cats.

you could find a private inspector...

You remove them cats and have a non legal CA emmissions vehicle... take it to a private inspector... fork over some $$$ and get that stinkin sticker...

Or get high flow cats... they are the same thing but the holes in the catalic material are larger...

Or... do whatever you want... but save your stock stuff... so when you go to inspections you can swap back to stock...

yeah ill see about that but i dont pass smog as is with my tunner. so if i did do that i would have to replace that and the new stuff. But that wont stop me thanks guys.

You will have no back pressure.............

ok so these cats we were talking about... does anyone have high flow cats or know how much they would cost me. I only know of magnaflow cats and they a pricey
