exhaust bolting question
 

My friend was installing his exhaust and had a hard time bolting to his cat convert, well he got 2 nice and tight and the other is tight but with a gap(not tight on exhaust) i think it got miss threaded.
So my question is will this cause a problem with performance???
Also, how can he fix it?????

i don't see why it would affect performance unless the pipes don't allign perfectly or it leaks.

nah they look pretty aligned
so then it should be fine
thanks
