LS swap exhaust set up (advice and pictures)

[fast&low]

Hello guys & thank you in advance for your time
Just finished my ls swap this past weekend & now I just need to get my exhaust installed so I can get her back on the road.
My truck is a 1969 C10 SWB with a lq9 Vortec MAX/4l65e combo with 2010 Camaro exhaust manifolds.
I'm thinking of having the exhaust exit right in front of the rear tires.
So I'm looking for advice and pictures of your trucks exhaust set up.
2.5 or 3" pipes?
X-pipes or H- pipes ?
Pictures and advice would be greatly appreciated.
Also this will be a daily driver.
Again thank you for looking and thank you for your time.
Miguel

Not exactly the same, but you can set yours up in a similar manner. A box o' bends from Columbia Mandrel was 85% of all I needed.

Hello BR3W CITY
Yes i looked at it after I posted & nice work really looks good but not only do I not know how to weld I probably wouldn't even know how to set up a welder.
I'm just going to leave it to the pro's
What size pipe did you go with?

[fast&low]

Sorry I just went back and looked at it 2.5

I use 2 1/2 for everything and I've never used a "X" or "H" pipe, especially for a driver. Do yourself a favor and spend the extra money that the "X" or "H" would cost and run the pipes all the way back, either straight out the back or behind the rear tires.

Just My 2¢ worth.....

Curious how that would be doing himself a favor though? Nothing to gain by going the extra foot...behind the wheel or after, it doesn't matter.

I dont think you will find too many fans of flowmasters I think they tend to drone plus other issues. I like the MF they are straight thru and IMO sounds great.

[fast&low]

I own a 1969 Olds Cutlass that I purchased back in 1996 with Flowmasters already on it they look & sound the same as the day I purchased the car.
A 455 Old's rocket with 3" exhaust & Super 40's Fliwmaster's sounds better than the New York symphony IMO
But I do respect your opinion thank you

[BR3W CITY]

Had magnapacks before and liked them...switched to DynoMax Bullets and am pleasantly surprised.

[fast&low]

I was going to ask you about them (DynoMax Bullets) I have heard of them but never heard them in person.
How would you describe them? loud or very loud
And what is it you like about them?

[Andy4639]

Well not the best pictures but I do have some. Long tube headers with dual pipes and Magnaflows mufflers. Sponsors of the HRPT.

It makes a lot of difference. It's actually 3 foot if you measure it but you are adding 5 foot of pipe which cuts down on drone and noise level considerably.... To me that is doing yourself a favor.

Any opinions on Flowmaster's versus MF mufflers?
At this point I pretty much know what I want I'm just looking for pictures of exhaust routing set ups so that I can show to the exhaust shop to let them know what I'm looking for.

You asked for opinions and that's all I gave, hence the 2¢ worth comment.....

Video of the new pipes.
I have to agree with LockDoc if you want to talk on the phone are to the passenger in the truck going down the road run the extra few feet of pipes and get the noise out the back of the truck.

Naw, I'm an a$$hole in real life, I just like trucks and they help me be less murder-y with my human interactions. I appreciate the kind words however.

As for the Dyna's; I'd say that they are actually quieter than my worn out magnapacks. They have a lower, less droney sound. In general driving conditions, I'd say they "tame" the noise that my old setup had. Under heavy accell, they have more of a lions growl than a wolfs bark.. .does that make any sense?

I have some good video clips of my new setup, but I can't release them yet because part 4 of my most recent series hasn't dropped yet. If you like, I'll rip some audio from them if you want to hear how they sound on my truck and not wait another week or two.

did you cut holes in your crossmember? how did you do that?

[Hart_Rod]

Good thread and opinions by all. I personally like Flowmasters for first Gen small blocks and Magnaflows for the LS stuff. Just my personal preference, but I've tried both and that's where I landed. As far as the length of the tailpipes, they are kinda like my socks, the older I get, the longer they get................. As far as the H pipe, going without it will give you more of a "Hotrod" sound. If you are on the fence about it, I would recommend going without it and if you don't like the sound OR feel you need more HP, have one installed as it's not that difficult to add one in. Just my .02. OBTW Fast&Low, you need to clean out your PM box, .

I have a Frankenstein for an exhaust system. Was a rush job to get my truck going. I have truck manifolds to 2 1/4" pipe into 3" pipe into flowmaster 44 and out the back by the tailgate and I friggin hate it!! It is way too loud inside and the drone is awful in my cab, so bad that you cannot have a conversation in the truck at certain rpms while driving on the freeway. I am going to have mine redone at some point with Camaro manifolds, 2 1/2 pipe, H pipe, and Magnaflow or dyno. just my experience.

[BigMike608]

On my 77 I used Camaro manifolds, 2.5" pipes, and Magnaflow.....

Here's a photo for those who haven't seen the available Hooker 73-87 LS swap exhaust system yet. It all tucks above the bottom of the frame and bolts right in when the Hooker engine brackets and transmission crossmember are used. I actually modified one of these systems and installed it with the Hooker crossmember on my 79' C20 long bed with great results, so it can be used in non-LS swap applications as well.[IMG][/IMG]

[fast&low]

Sorry guy's for the late update.
Well I already had the 2010 Camaro exhaust manifolds so I went with 2 1/2 inch pipe no X pipe or H pipe Super 44's with chrome exhaust tips coming out right in front of the rear tires on both sides.
Yes it's loud & yes I love It
Thank you all for your time and opinions
