Got the SLP LT's installed, off-roads (for now), custom 3" Y-pipe in too. Been drivin the **** outta her cuz I love the power and the sound they make!! BUT: sitting still, engine idleing, I can hear what sounds like my lifters ticking away! Never heard it with the stock exhaust system. Am I headed for a valve adjustment? Or, is this normal for tuned LT's? Your opinions please... <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Probably your check valves flapping from too much air flow. Here is a cheap mod to fix it which involves adding restrictor plates to the air tube connection:

Am I headed for a valve adjustment?

Sorry, you have a non-adjustable valvetrain.

I have the same setup and I have the same noises!
It was really driving me crazy but I have tried
a number of things to fix this problem
and have not had any success.
A lot has been posted on this subject so you may be able to find some info by doing a search.
I still think it is an exhast leak but untill
I remove the header and put the vehicle back to
stock I don't think I will be able to know 100%
for sure that this is the problem. Good luck,
you frustration level will decrease as time passes <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" /> <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

One more thing, if you haven't done the AIR pipe
mod that is noted above do it! I had a noise on accel from about 1800-3200 rpm that wentr away after I put the restrictor plates in.
