torque specs for exhaust bolts?
 
Hi I just got some CNT downpipes and a y-pipe. Could someone tell me the torque specs for the various bolts and nuts? Also any tips for preventing exhaust leaks?

I installed a y-pipe with new gaskets but put on a thin layer of high temp gasket maker. Now I have an exhaust leak that you can only really hear on a cold start and goes away after a min. I got some new gaskets for the downpipe but is it ok to re-use old gaskets (1 month old) for the y-pipe? or should I go to the dealership and buy some new ones?

just tighten them as hard as u can with a hand wrench. shouldnt have any issues with leaks as long as u can muscle up on a wrench.

forgive me if that sounded redneck, but i wouldnt worry too much about torque specs on an exhaust.

gaskets will by fine to reuse if only a month old

EM-38 fo the FSM states that 22ft lbs is the torque spec (to tighten a nut and fasten an exhaust manifold to the rods fastened to the crank case).

------------------------------

EM 39 states that the tightening sequence is as follows:
( the sequence as i post it is relative to the picture)

Drivers side

<--- Front of car
3286
514 (you will go back and tighten "1" as the 7th step)

Passenger side
Front of car --->
6283
415 (you will go back and tighten "1" as the 7th step)

------

The bolt rods appear to be in the same order.

Torque specs for them on EM 38
11 ft lbs
