Best Headers and Exhaust Combo?

[FF2NAC]

I had American Racing Headers with the off-road pipe hooked up to a Corsa Sport Exhaust, I had to change the midsection to a high flow cat because it was too loud and raspy.

 

It helped reduced the sound by 25%, but still has an extreme rasp to it.

 

I'm looking for a new setup that will eliminate the rasp with the long tube headers, let me know what you guys have, thanks.

The Corsa Sport is a lot of the issue. I love Corsa (I have the touring with off-road Y and Thorley headers). Not nearly as raspy as the Sports I have heard, but still there. I'm planning on trying a resonator behind the muffler as a cheap fix. Magnaflow makes some good ones. Otherwise I will switch back to muffler that has sound deadening insulation (like a magnaflow)

I was thinking of switching to a touring muffler would help, but I guess not. I heard good things about Magnaflow, I wish someone has a video of a LT headers with Magnaflow.

Not a NNBS, but here is my 2004 back in the day, before I put on a blower and Corsa Touring exhaust.

Sounds great Jenna!

 

This is how my setup used to sound, only mod after this was a change to High Flow Cats, still has the rasp, but just reduced the sound.

My 04 had Magnaflow high flow cats as well. The cam probably changed the sound a bit though.

I will have my Kooks/Offroad-Y on this weekend but it will be mated with stock exhaust. I'll report back this weekend if I get a couple free minutes

I would recommend the Magnaflow with resonator in the tailpipe. You will have deep rumble when accelerating and quiet driving when cruising.

Kooks are on... I'll tune it tonight and report back with a sound clip. I'm actually modifying the Y-pipe now because it was for a 5.3 so I'm dragging out the 309 wire and upgrading the output side of the Y-pipe to 3.5", or 4"... We'll see what I have room for.

Awesome setup TDT! I'm sure it'll sound mean.

 

& BuyAmerican, that's the route I'm most likely going to. do you think I'm able to keep my Corsa pipes but just swap out to a Mangaflow muffler?

Probably. The Corsa is pretty long muffler though. You may have to add some pipe to make up for it.

 

If you go magnaflow don't be surprised if you have to add a resonator. They sound great, but are bad about drone without one.

I've had a ton of different exhaust systems on LS type engines,

In my opinion corsa sounds like a boat, hate the sound. Borla is so smooth, Dynomax sounds good, magnaflow is good also with ORY's

If you stick with the corsa high flow catalytic converters are your friend.

Yes, you will be able to use the Corsa pipe with a Magnaflow muffler. On the 14-15 6.2L trucks, Corsa is a center in/center out and Magnaflow is an offset in/center out. It will fit, but you will likely need the help of a muffler shop and some custom made pipe.

Louder than I expected with the stock exhaust. I just ordered the Kook's with an ORY. If the dynomax is too loud I'll add a 22" Magnaflow.

 

So the y-pipe was the wrong one?
