LS Swap Exhaust
 

What are you guys doing for exhaust for your LS swap? I am running 5.3 ls with speed engineering long tube headers.

I have looked at speed engineering kit and hooker blackheart but just havent heard them before so trying to get some feedback before choosing what i want.

Goal: have a nice rumble for shows but i plan to drive and dont want it crazy loud in the cab when going down highway.

I used the speed engineering swap headers with a 2.5 inch stainless bend kit. I cut and welded up my exhaust with Summit racing 409 stainless 2.5 mufflers 14 inch long i believe and 3" flowmaster prebent tailpipes on my '77 k20 5.3. I didnt put in a x or h pipe, just true duals, because I was in a hurry to get it done. It sounds fine, gets noticed with the stock cam but it think its a bit loud at wide open. I dont think ls engines sound have a good sound anyways, so its all personal preference.
It cruises nice on the highway at 80, no drone or buzzing. Ive done 600 mile trips several times and its quite enough for what it is.

I have a '13 (gen IV) in a '86 C10 and I used Pacesetters "shorty (block hugger) headers and the stock cats (w/ all 4 O2 sensors) and had a muffler shop do a "custom" exhaust with Xpipe and exit each side in front of rear tires.

I'm running headers and duals on mine..turned down in front of rear axle..
Not crazy loud, but has good tone..
The are magnaflow knockoffs, called magflow, they've since changed the name to maxflow..

I'll see if I can get some videos posted too. I've got an '85 with the 5.3 with Speed Engineering 1 3/4" headers. I bought an amazon X-pipe piece and a pair of Borla ProXS mufflers. Had an exhaust shop bend me up a custom 2.5" exhaust all the way out the back. Sounded really good, had a mellow idle but a very unique sound at WOT

The ProXS's started droning worse and worse as time went on until I couldn't stand it anymore. So when I swapped in the T56, I swapped to some universal Corsa's mounted behind the axle. They're entirely too loud on the outside :cf::cf::cf: but they're very quiet inside. Gonna add some resonators to tone it down a touch and calm down the part throttle "clap" they have but overall this is much better than the first setup

Here's the old setup with the Borla's when they were knew. Didn't even have 10mi on the swap at this point lol
