I have a 95 civic si and I'm getting my exhaust put on. Just wanted to confirm, can you run the stock cat with hi-power?

 

Yes, most are designed to be cat back and should bolt right up.

 

perfect thanks

 

Yes stock cat will work

 

yep, i've got the HKS Hi-Power exhaust on my ej8, it's a direct bol on

 

turns out the seller didnt let all the info out. it seems like this is for the 92-95 civic but for coupe. if anyone's interested in the catback, pm away. asking $250

 

take it to an exhaust shop and make it work.

 

^~~~~the exhaust should be very similar and an exhaust shop can make it work. being its for a coupe it will jsut be a few inches longer on your straight mid pipe and would be easy for any exhaust shop to do. i like the hks hi power because it comes coated and less prone to rusting out. ive had my hks hi power for 5yrs and hardly any rust. matting it with a random technology hi flow bolt on cat would make ur power gains alil better. and best of it all it all bolts right on. i put a header,cat,and hiflow on all at once when i did my ej sedan and i definitely noticed the power difference from a stock dx exhaust system. i just google a direct bolt on random technology hiflow for 205 dollars. it would be a good investment vs the stock cat.

 

thanks for the suggestions. thats def gonna be less of a hassle. apexi rsx are you absolutely sure on the only difference being length? When me and some mechanics were looking at it, it seems the bends weren't fitting around the suspension but we were only holding it up to the old exhaust

 

all the suspension components are the same and interchangeable it should fit. just cut the straight mid pipe and weld a flange on for the cat. the hangers may need moved, but they shouldn't the mounting should all be the same.
