sd headers question

[Grimsin]

How many band clamps do I need?what size?
What ones do you recommend?

[Fivefingerdeathpunch]

Two 3in clamps.

Two 2.25in clamps.

If you are installing a cat converter, things might change.

When I did my headers I ordered these ZZPerformance - Stainless Exhaust Clamps #ZZ-SECLMP

[BillBoost37]

If frozen boost has them in stock $5 each.. otherwise..yeah

[Grimsin]

Deleting the cat.
plan on going from the SD downpipe to 2.5" pipe to my catback( catback is 2.5")
My buddy is bringing his welder to weld everything under the car.. so do I only need the two 2.25" clamps?

[Grimsin]

Who is this frozenboost? He have a website?

[Fivefingerdeathpunch]

SD headers already come with a reducer to bolt straight up to catback system.

But if you wanted to weld the 3in test pipe where the cat is going to be, then you won't need those two 3in clamps.

Then just get two 2.25in clamps for the crossover.

V-band and straight clamps are almost at the bottom of the page. Scroll way down.

I went to the local O'reilly's and picked up a couple clamps and Copper RTV and was done with it.
