To start, the only issue was the fitment on the drivers side with the intermediate steering shaft. Had to grind a couple cm in one spot of it. I believe this is due to my '99 having a groved shaft rather than a straight one on the newer trucks. Other than that there were no problems for my ecsb 2wd.

I noticed a noticable SOTP difference in power over my old stock manifold, no cat, bullet exhaust. Even with the big case 22" MAGNAFLOW I bought from AP, the shift extention went from 4900 to 5100 rpm. The night I put the LT's and ORY on I went for a test drive with no muffler and it screamed like no other. My truck has not been retuned yet for the LT's, but still there is a noticable difference mid range & up top of 2nd and 3rd it pulls a lot smoother. These headers really let this 6L w/ 230/234 cam finally BREATHE.

Me & my friend went out with his tom tom & through the magnaflow on a back road hit 142 on the gps but ran out of road still pullin though.

Overall, I am happy with the performance gains even with the big muffler I put on & not tuned for them yet.

For the $$ these headers can't be beat for the performance & the LOOKS. Very nice looking headers. I picked them up for 470 shipped from speed eng..

Thumbs up for these LPP's.

 

I love mine on my dd crew cab and I am about to get them for the race truck. I had no Idea anyone was reselling these things. They are cheaper through speend eng. the lpp them self. I just have had bad luck with the pacesetters on my race truck.
