alright guys...i need EVERYBODY's ADVICE

First of all i have an 08 silverado single cab with a 5.3L

i just bought a D1 procharger with 60# injectors and i want to get longtube headers before i install the procharger and get the tune...

1. How good are PACESETTER longtube headers?
2. Is 1 3/4 fine or is 1 7/8 any better?
3. Do i need a Y pipe?

I really don't want that check engine light on...so does that mean i need to keep my 02 sensors and my cats?

THANKS for any advice

 

For the money, pacesetter is king in my book.

The 1 3/4 should be fine for the D1. I ran 10.40's with a D1 with 1 3/4' pacesetters.

Yes, you'll need a y-pipe

Your check engine lights will/should be handled in the tune. My personal preference is no o2 sensors and tune in open loop. But keeping the o2 should work fine.

Ditch the cats with forced induction. They won't like the a/f ratio that a FI combo needs.

 

PACESTTER sells TWO diferrent Y pipes #82-1176 and #82-1177

Do you know the difference?

And thanks for your help
