I need help figuring out what is wrong with my 1994 nissan skyline R33 GTS N/A (Rb25DE), I will be driving and suddenly all power cuts out, car does not stall, lasts a good 1-2 seconds before power coming back in, does not happen constantly but is starting to happen frequently enough. The car doesn't have any issues at idle. Any help would be appreciated

Thanks

4" cat back

Yeah it's how it come from the previous owner

Exhaust help Hey everyone so I own a 1994 r33 gts skyline as a daily and when I got it, it came with a 4" Just jap cat back system, I've recently found out that I have a leak in my exhaust but it's coming from behind the cat, and I'm stuck in debating wether or not to replace the problem with extractors, but some people have told me I'll only be getting restriction due to my cat and have told me to get a hi flow cat, Would anyone on here be able to tell me where I could get a 4" cat for my exhaust and extractors and what brand extractors I should get? I've been looking at just jap ones I'm located in Wollongong NSW but have no problem traveling to the city
