Your spark plug wire routing is a thing of beauty. Great deal on the mufflers, too. GLWS. smile

Thanks Brad, you make more power when your wires good lol! I hate messy wires.

 

I'm going to reduce the price to 150 for members here.

Basically, you get two for one.

Are they for mounting directly to headers or are you using some sort of an adapter?

Bolted a flange with a 2.5" pipe on the header, and used a Band Clamp to tie the two together.

Hmmm..I'm wondering if these will work on my Chevy pickup. I'm going to be installing a complete exhaust this year.

They will work on any pipe with the proper adapters Todd. They are 2.5" in/out.

I'm thinking more about the offset of the pipes themselves and I need to research if true duals will work on my truck. Typically you'd use this muffler:

Mark,

Nice deal on the mufflers. Too bad they are 2 1/2 ". The system on my Catalina is 2 1/4" all the way from the long branch manifolds back.

I think true duals would be custom on your truck Todd.

They are easily adapted to 2 1/4 with reducers Bill.

 You need to be creative to get two mufflers under there. Gas tank runs on left side. Here's a 1996 custom set up.
