just finished ordering some Pacesetter LTs and wanted to get any feed back on these before bolting them up...did you feel/see any diffrence at all? My truck is basicly stock exept for the cut out, but i am planning on gettin 3"ory, under drive pulley, intake and tune.

 

I felt a difference when I installed them, but I already had a tune. After the tune was adjusted for the headers, it felt even better

 

Too really take advantage of the better 'breathing' you'll want to tune.

 

I noticed a little difference with just int and header, no cat, 2.5-3. The magnaflow gave my bottom end back and it felt even better. put em on and never look back

 

Didnt really notice much until after the tune was adjusted for them.

 

so the tune is a must after the longtubes... cool thanks guys, I have another question, will my stock L60 hold up with the mods i listed? will a shift kit/servo help it at all?
thanks in advance

 

IMO yes it can hold I saw a magnacharged sierra run 10psi on shift kit and servo not to mention intake and headers


Installed a PI 3600 stall with alto red eagle ,Shift kit hd-2 and a vette servo Havent tuned it yet for those things but without tunning I noticed that the shift kit and servo made the shifting fast

I'm installing a cam next week too

 

thats pretty awesome DD, wish i could do all that at the same time. Well their finally here check them out.

 

try get some dyno runs before and after to see if it really was worth while.. i contemplating them for my yukon in the near future

 

take your time with the install too... lol. I bent one of my collectors out of frustration on my install. ory pipe wouldn not fit on after that. then my ring clamps came loose and accidentally drove over branch during ice storm knocked the pipe loose... so maybe some band clamps or minor welding would be a great idea after fitted.
