Muffler and Cat delete pipe possible issues?
 

Hey I recently purchased the Diamond Eye muffler delete pipe, as well as the MBRP Stainless Cat delete and something just dawned on me today. I dont know exactly how the system works but from what I can tell the pipes I ordered are fabricated to fit over the already 4" pipe on the stock exhaust. With that being said theres no such thing as a 4 and 1/4 in clamp to fit that? What size clamp will I end up using for this I had thought it would be 4in but that obviously cant be. Diamond Eye does make a pipe designed to fit inside the pipe as well. The question I have though is what size clamp Im going to end up needing? Fleet Farm carries 4" clamps but if its an exotic size then Id like to make an order right away I figured Id ask on here because im sure theres someone thats ran into this perdicament? Thank you.

Wouldn't they supply the clamps?

Band clamps work very well. Just about every auto parts has them, as well as truck stops, diesel performance vendors, ebay etc.......

No they state right on the item that it does not come with the clamps which kinda sucks.. But now those band clamps i notice those are more common but i was skeptical on using them... I think they make more of a variety of those?

4" clamps are what u need.

Alright I was just thinking about how i rememembered there always a little bigger then the size they call out must be for this reason. Thank you!

I did the same thing to my 06 and just had pipe and muffler welded on. never had much with the clamps.

Band clamps actually work very well.

I would have welded it if i hadnt got the stainless cat delete but you cant hardly go wrong for an extra 5 bucks.

With the Cat delete, you should experience cooler EGT's. Thats always a good thing. :tu:
