Pacesetter Headers?

SeekAndDestroy · March 8, 2022

I see Pacesetter makes long tubes for K2's now. I'm thinking about getting them. They are a good price, about half of Kooks.

Does anybody have these on their truck? Or has anyone used Pacesetter headers on another vehicle?

Just curious about the quality, fit and finish, compared to a top brand like Kooks.

Part Number: 70-2268

Speed Engineering imo

Way better

Save your money on headers unless your truck spends most of the time at WOT that's the only time headers benefit.

Not really.

The stock exhaust is pretty well thought out in terms of flow for "normal" driving. Gotta keep the EPA overlords happy.

True. Headers just add some good sound and allow for better flow in case of future upgrades.

I the EPA and would never modify my car's emissions!

I agree, stock is boring. Doing a cam swap and I want a custom exhaust, Lightning style exit.

Do you have a set of Speed Engineering headers? I am leery about them because the price is so cheap. $410 compared to Kooks at $1800, and Pacesetter at $570 (CAD)

Yes I do have a set but on my GMT-800. They are fantastic and their customer service is great. I know a lot of guys who run those headers and have had great success.

My experience with them on my truck was I had one fitment issue with the headers touching the frame. I believe we have narrowed it down to me having a franken-frame because I own a first year, 1999, so it just was unluck of the draw in that case. They are great to work with though and are ready to help always. Hell I hit them up almost a year later and told them my issues and they were happy to work with me.

I would go with american racing. The cost of kooks headers has pretty much doubled since I bought mine, its insane. They even have a shorty header they've priced at a grand USD. ARH pricing has remained the same. I've heard their standard high flow cat is more durable as well.

Although, even when you're running high flow cats you WILL choke out people behind you. Not an issue when the weather is hot/warm, but when it cools off in fall/winter/spring (most of the year) nobody will drive behind you. I learned this the hard way by trusting the internet, "Ah yeah, I can't smell anything; green cats are a waste of money". And now a green catted y-pipe from kooks is like 2 grand cdn or something

*edit*

I just wanted to add exhaust smell with race cats is more of an issue with gdi engines. Port injected it seems to be less of a problem.

+1 for speed engineering! Find a good welder near you and have them weld on 3" v-bands at the collectors and y-pipe. Mock it all up and then have them weld the center portion of the y-pipe. No leaks, better clamping, and you still spent less than half of the big name brands.

dont have any long tubes installed, but I believe doing so will shift the entire torque and powerband upward about 1000-2000 rpm higher... that doesn't impress me for another 15 hp..

Not quite. Longer primaries generally promotes lower RPM scavenging. However, larger primary diameter does shift it upward, and it changes some of the lower RPM part-throttle transient torque production.

It's complex, really. Most oversimplify it but it's a beast of a topic. I've read several books by the master David Vizard and it's mind blowing!

Is it worth it to me? IDK! I want to see how my heads/cam setup works with stock manifolds for a bit first. It might be all I've ever wanted. The problem for me, and I'm sure others, is that a LT header setup will necessitate a different cat-back setup because my Corsa system will be entirely too loud.

This one above ^ is a 6.2 Yukon Denali with an aftermarket cat-back, S&B intake, and a Pat G tune. The baseline was before Pat finished up his tune.

That's a considerable difference! 26 HP and 32 lb ft. And gains all across too.

I realize that this is two different vehicles on two different days - but just an illustration.

I think i can make 25hp with the stock exhaust cleaned up and using the stock manifolds... just need a catless system and highflow mellow sounding muffler. stock is very restrictive due to emmissions and flapper. I wouldn't use any pipe larger than stock for a 5.3, maybe a 6.2 can go up on the exhaust by a half inch

David Vizard is very smart guy, but he likes to over complicate things to make himself look wizard like to gear heads.. i know a few other tuners like him they can be a PITA to deal with, after all it is a business, and they like to separate the fools from the greenbacks
