I have been wondering how loud is a lightning with stock cats
and no muffs just straight pipes? Is it long trip tollerable, more or less, on the in cab resonance is there alot?
Thank's

 

I would say it would be to loud for long trips without mufflers.

I would do one of the catbacks
silverbullet or bassani

They both sound awesome

 

It's pretty loud and not for the faint hearted. I run the exact setup you're talking about with 2.5 inch stainless steel piping, no mufflers, stock cats, etc.

It is LOUD and there is a drone on the highway. I don't mind it much but if you take long trips a lot I wouldn't recommend it.

It does get attention around town though

 

Thats what I needed to know.
In the past I put a borla single pipe aftercat system on our expidition, It was almost the same as the stock system.
Very disapointing. I am sure the lightining will be much better.
Thank's for the info.

 

Now that I'm a little older, no muffs is a little too loud, but hey I've got to hold my own agains't all these trucks with exhaust up here.

Its not a truck unless its got aftermarket pipes somewhere underneath it.

I think I might have to get baffled tips...

I am not gonna argue with .28 better ET thats for sure!
