Default Plugs & Cutouts

Hey Gents,
What plug do you reccomend. Is the irridium worth it? What special tools do I need for aplug change?
I want to put a cutout on, I have the 3" Y- pipe & CTR. mount exaust fro SLP. Do I need the 2.75" or the 3" cut out.

Thanks!

Rich

Getting to the hard to reach ones is best done from under the car.
3" cutout fits on your 2.75" I-pipe, in the well/niche/void under the passenger seat.

My SLP CME I-pipe is 3" diameter (like 3-1/8" OD). It
crushes down at the Y-I union to conform to standard
Y diameter.

Here's my installation:

#8 plug is the bitch, most have to do it from below
(unless you've gor arms like a spider monkey). Headers
change that (my Jet-Hots leave no access from below
but seem to have opened up room from above, slightly).
Getting a gear wrench & stubby socket or a flex-head
ratchet may help you out.

Thanks for responding. I installed center mount exaust & a 3" Y-pipe myself. I could not remember if that kit included a larger I pipe. Short of calling SLP, do you know if that comes with a I pipe? You stated that I would need the 3" cutout, and I am only asking this because I want to order the right size.

3" is fine.
Even if the SLP CME, is in fact, a complete catback, as mentinoed above, 3" is still fine to weld in place.

Thanks again!
as I get deeper into this thing it snowballs! I am wanting to put a header,cam combo together. Should I use the stock heads and modify them, or go aftermarket? My goal is: 450h.p. It is not a daily driver. I was thinking 224/234 comp. cam. If I go with L.T. headers can I modify the 3" Y-pipe, or do I have to purchase a new one?

Thanks!
