hello, ive got an aftermarket exhaust cat back on my 94 classic wrx. However if i look down the engine bay, near the air fliter, i can see where part of the exhaust joins (after the turbo heading toward the front of the car) there is a bolt missing and a slight gap, and blows a little (looks like it might be where the pipe joins the cat). has anyone got a pic of the standard exhaust system on and early model so i can see what i need, im hoping its just missing a bolt and not sheered off! or just the size and pitch needed would be fine. ill try get some photos later.
thanks

 

heres some photos of the pipe where the bolt is missing, theres a yellow arrow where it should be............

 

ok ive got the bolt sizes and managed to get some to try in work. I can get my hand down there and put it in but theres no way i can get a spanner or socket on it! i can touch it from underneath but the heat shield is in the way so once i can get underneath ill see whats what
