Another happy customer!

 

I would like to point out that it doesn't sound like the guy who bought the $1400 headers had more issues...... Although when Pacesetter has a Y-pipe for the 6l80e it would be a better comparison.

 

If ARH would have sent the correct Y-pipe to start with, we'd have been done in less than 3 hours.

the #1 and #3 tubes are EXTREMELY close to the steering shaft. Had to use a cutoff wheel to remove the protruding threads of the upper pinch bolt and part of the pinch bolt spring-steel flange nut.

The battery cable to the starter solenoid had to be relocated forward.



Yeah... my simple Y pipe issue vs those. I'll go ahead and say I had less issues.

 

I would say for most people welding seems like much more of an inconvenience than cutting a bolt shorter and loosening another bolt.....

 

Yep!

The mods I had to do took less than 15 minutes total. No big deal. I've been doing this kinda stuff since 1973, so I EXPECT a few issues with ANY aftermarket parts.

To be fair to ARH - they are by FAR the nicest and best fitting LT headers I've ever installed.

 

Pat Guerra is the man! You'll love his tune. He REALLY knows what he's doing. He did an outstanding job on my cam'd GTO I had.

 

That's what I've been reading!

Plus - Pat's been experimenting with the VVT tables on his wife's YD - optimizing for torque instead of fuel economy. He sez it REALLY wakes the 6.2 up!

Can't hardly wait for the 9th to get here!

 

For you guys that are running LT's with stock cat-back... Do you have any video clips out there somewhere? I'd love to hear that sound. This is the route I plan to go.

Also is there a big difference in the systems that have the catted y-pipe and the ones with resonators that look like cats? Seems both would throw codes.

 

I put the 99-07 classic LPP Longtubes on my 07+ truck the week after christmas. I did it by myself with a 3/8" ratchet and a 1/2" torque wrench lol. It took about 5 hours by myself doing that and texting at the same time.

I've installed, ARH, Kooks, Stainless works, Ebay headers and now LPP now on various different vehicles and these fit just as good as the $1500 headers and I only paid $450 shipped (got in on group buy for christmas special). They're normally $500 shipped.

That being said, the one thing I dont like about them, is the coating. I wish I could have got them with a raw stainless finish rather than the polished stainless finish. At any rate, they fit awesome and didn't have any fitment issues. I put them both in from the top down.

 

The sound is simply awesome. I've always LOVED the sound of the stock 6.2 exhaust system, and with the headers and high-flow cats - it's even better! I wouldn't change my stock cat-back even if I would gain 20-30 HP, and I HIGHLY doubt that would be the case anyway.

Can't speak for any other header company's high-flow cats, but I'd imagine they're all pretty much the same. They are quite simply TOO SMALL and apparently flow too well to adequately reduce the emissions enough to keep from setting catalyst efficiency (P0420 and P0430) codes, and of course the OR Y-pipe will set codes as well.
