As the title states, whats the average install time for test pipes on a G37 Sedan

 

assumin you have no issues taking the top bolts off the cats, an hour and a half. If you have issues, which 99% of people do, all night.

 

Had my HFC's put in professionally in about 45 to an hour. (that was with the demon bolt issue) if the issue didn't apply would have taken them about 30 mins.

 

correction, all night if your a noob like me and too cheap to pay for instal

 

lmfao ^^ It's all good I'm a newb too! I was planing on doing it myself but after hearing all these issues with that demon bolt... I was like f*ck it i'll let my boy who owns a shop take care of it lol.

 

expect to break two bolts.

 

Pb blaster to the deamon bolts about 24 hrs in advance, then again after 12hrs then once more after 6hrs, make sure engine is cold before attempting removal of the bolts. empty the remaining pb blaster again onto the deamon bolts.
Then install should not take more than 45mins

 

Get swivel joints, 1/2 extension, and 1/2 drive wrench. 3/8 drive flexes too much.

 

Excellent advice. It may seem like overkill, but I go a step further. Soak all the bolts generously in PB after you park for the day and let it soak overnight. Do this for 3 days straight. Then follow Presto's advice. Trust me, it makes all the difference. Also use the proper tools Modme said. I wouldn't even attempt this without 1/2" or larger impact tools. Work slowly and carefully.

 

sounds like fun
