Test pipes are just pipes. They are empty hollow pipes. You should be able to notice a crack in a pipe. Check particularly around the ends of the pipe (exhaust flanges).

 

my helix test pipes cracked too =(

 

I was looking at high flow cats, but I have NISMO exhaust. So this does not seem like a viable option. It seems the design of the NISMO y pipe does not give enough flex...

I guess a good option is to replace the Ypipe with the motordyne pipe, and see what happens.

 

Quick question guys, i have the Megan longtube headers and it has that brace that bolts up to the oem cat support brace. The problem is i lost the oem brace because my previous TP did not have the option to use the oem support brace. My friend has had the same Longtube headers for a year now with no cracking and he's using the oem support brace. Do u guys think i will have a problem with cracking my longtubes? This will be a major problem cuz if they crack, that means i have to replace the whole headers which is a PITA lol. I have the Bassani TD Exhaust with an X pipe.

 

why would u risk it, just get the brace and do it right once..

 

^ true, do u know where i can get em? I've looked for a used set but none.

 

get new ones from nissan or other sites to get parts from, or check junk yards for any z's or make ur own, idk, im sure there are some to be found and might even get someone on here if u put a thread up in the wanted section for them..

 

^K thanks man, just started a new thread
