Custom Cat Back i have 2.5 inch piping..and universal hks hyper exhaust. i was wondering..is there a point puting an high flow cat? and will this have gain ? or it's use less. thanks.. |
noticable gains |
this is off topic to the question, but more a question for 1028CiViC: How do you like the Hiper Exhaust? Im gonna get the full cat-back in June, just wanted to know your thoughts on the system. How does it sound? is it real loud? deep? Smooth? Is there generally a difference in sound from a custom setup and a full cat-back? Keep it real. Peace~ |
keep us updated on what u do and how well u like it! i've been thinking about doing that too! |
the only difference between full cat backs and custom is a name brand. For what most people do with there cars, a custom cat back is good enough. Sometimes, customs are better than full. If you want hi flow with a custom, get 2½ inch piping, that should be the equilvalent to 2¼ madrel bent piping. I paid $200 bucks for my exhaust(installation and muffler, 230 if you add the resonator removal which I should have done the first time). |
but should i add it..and is there gain? |
No noticeble gains, I have a highflow cat. I had to install it because the HP racing cat I had there before made the system way to loud. Remember you need some back presure. I think 2.5 is to big for a mildly modified engine. If had a turbo that would be a different story. |
