Custom exhaust questions

[drakon543]

ive had flowmaster on most of my trucks except my current 97 has a thrush flowmaster knock off. i like the flowmaster force 2 systems as they have a nice little growl to them but are friendly on the highway. but ya everything from the american thunder on a 91 Camaro and a true dual no cats flowmaster 40 setup on a pickup dumped righg after the cab. down to custom diy stuff and the flowmaster force 2. i like magnaflow on smaller engines but not on v8s. gibson has a nice sound also. but as noted above regarding an all steel exhaust they will rot out. if you do go all steel run the truck for a week or 2 then get some exhaust high heat paint and coat the whole exhaust. next morning it will have a smell as your running it but once the smell clears it will last alot longer. i dont even bother with a steel exhaust anymore unless im doing a cheap diy system or a cheap diy repair. stainless steel exhaust is so much better.

Ok so I just had both cats removed on my 04 z71 4x4 since they failed


For the love of God Run steel and not worry about rust. I am about to swap engines to a 408 in my 05 Denali XL and have decided on custom side pipes. Don’t know which mufflers I will use but I have to run cats. Anybody ever done that?


Now that I started messing with the exhaust It got me wanting to do a custom exhaust. Few questions

I have my mind made up on flowmaster, Single in dual out


Not sure if I should go with with a pre bent flowmaster system like this one

Or go with a custom made one from an exhaust shop.

If I have the shop make me a custom one I’m also not sure if I should go with super 40’s Or super 44’s

And one last thing, where do you guys prefer to set the tips? Coming straight back out or to the sides? I’ve read if you have them placed going out the sides then they get dirty from the tires.

When I called one exhaust shop he said he preferred not to do the custom exhaust because of all the gas lines and hoses off to the left of the truck. And it would be hard to mandrel bend the pipes. The other exhaust shop I plan to take it to said they have no problem doing it

I’ve watched lots of videos and looked at pics.

I think I’m leaning towards going with custom 3” and having the tips come straight out. Not sure between super 40’s and super 44’s

It’s been a while and haven’t got around to doing anything to the exhaust but for those new to the thread, I had both my cats cut off because the honeycomb came loose so I seen my exhaust guy the other day when he stopped in at my work and told him the exhaust sounds like shit. I told him I decided on getting a borla muffler and he recommended getting a borla resonator also. He said that should change the sound up and make it sound pretty good

Couple questions.

Should I just get the borla muffler and skip out on the resonator or should I also get the resonator?

What is the benefit of the resonator or is here any cons to having one

Anybody have a borla series or model you recommend for our trucks? Part number would be helpful

I’m going to keep the stock exhaust pipes and just go single out. I was considering doing a dual out probably going to pass that idea up

I have the borla on my 6.2L which has stock 3.5 pipe, I like it, I had the flowmaster 50 series on here for a while but at WOT it sounds like shit
the Borla I have is a straight thru design, it is sort of passive / aggressive, quiet when cruising but has a nice growl when you get on it but not excessively loud
I guess you could say it has some drone if you are going up a grade and at certain rpm's I did take off the rear resonator but the 6.2 has a middle resonator also which I left in place
model: Borla 40946 XR-1 Sportsman Muffler 3.5" Center-Center 16"x 4.5"x 7.88"

Can anyone confirm if this will be a direct swap? I do not know how to shop for mufflers with inlet/outlet and location. Can anyone tell me the location of the outlet? I believe it’s a single in and out for that part

The stock pipe diameter inlet and outlet if i remember correctly is 2.75 inches but if you`re having a shop doing the swap they can make up an adapter to make it fit. I`m not sure about the offset on the inlet and outlet though.
