any tricks to finding exhaust leaks with freshly installed lpp with ory? I just can't seem to track the little ones down... And it's annoying!

 

Have some buddy stick a rag, hold it in the exhaust pipe, get under the truck, listen for leaks..

 

Good idea... Will try that....wish I could use like a smoke of some sort...

 

are you sure it is not collector noise?

 

Collecter noise? Not familiar with that...

 

Additional noise you get with headers vs. cast iron manifolds. Some headers are worse than others. The pacesetters I had were pretty loud but didnt leak.

 

LT's have a fairly loud tick by nature. I think the bigger the primaries are the louder it is. I had thorley headers on my old 350 and I never really heard much, but those were 1 5/8" tri Y headers, my new 1 7/8" ARH are much louder and honestly annoying at times. I'm really **** about this kind of stuff though. The thinner and longer pipes echo the sound of the valves. My guess is if you climbed under the truck and listened you could hear the tick echoing through the pipes. I thought I had an exhaust leak for the longest time... it was just something I had to come to terms with.

 

Seafoam

 

engine off , put some flower or any other powder on the posibol leak locations and let some body start while you watch where the puff happens

 

I heard seafoam was terrible to use in cars....
