I want to keep my stock exhaust or leave it to as quiet as possible cause having an exahaust is annoying and dont want it anymore. But I wanted to still put headers on. Can Headers fit on my stock exhaust without any mods to hooking it up?

Yes but they wont provide much extra horse power with out a enlarged exhaust.

 

might not be 100% bolt up, but it will fit.. most accord headers have crap for collectors, so it wont be that bad..


you a tad of connecting work and your good

 

do i have to mod anything or straight bolt on?

 

IMO exhaust won't make your car that much louder....I currently have 2.5" mandrel bent tubing into a mangaflow muffler and its really quiet, I don't think a header would make it much louder. But going for a header to a stock exhaust you would have some modifications but I would just do exhaust plus header for best performance If its too loud you could throw in a resonator and should be good to go.

You dont need any modifications done. I had a Greddy SS header on my cd5 with stock catback and it bolted rite up, no mods necessary.

 

Get the header and an Apex WS exhaust itwon't be much louder and will give you the extra airflow you need.

definetly...


since he already has an ex which has a 4-2-1 manifold that's is already pretty good, that any extra gain with an aftermarket piece will be null do to the stock exhaust. you would be just moving the restriction a little bit further down the line.

 

Isn't an exhaust just from the cat-back? Why would having the stock exhaust be any different than having an aftermarket one? The header still bolts up to the same stock collector doesnt it?

well if your cat outlet is 1.80" ish.. and the catback is 2.5 or say even for turbo 3", that wont bolt up:

2.25" is his best bit to get it close

true the aftermarket header is designed to bolt to the stock cat, but between the stock muffler and it's small piping you still have restriction in the system. the stock pipe is ~1.8 inches v. after market pipe is 2.25 or 60mm along with a better flowing muffler. so you may have rededuced restruction from where the exhaust leaves the motor to the cat, but after that it still gets restricted pretty much negating your gains.

not always, 99% are designed to run to the stock location, not always bolt up to the stock cat. Using the stock cat location is the easiest and most common way to get a good exact length, that will fit and no have as many hassles.. todays market there is swap, after swap, after swap, etc...

well i'm talking about the dc, greddy, and generic brand header that most 99% of the people buy. obviuosly there are small production header brands that make a header for special applications like the SMSP guys which would not bolt to a stock cat, but i didn't think we were talking about that 1% of the market here.

 

and Yes headers will make even a stock exhaust louder than just the mani. maybe even more of an annoying sound, kinda pingy

i agree, agian, it all depends on the one you buy:

Most are now coming with at least a 2.5" collector, DC is starting to, after their jdm headers hit off so big, greddy's is i think 2.25, as the same with hotshot, and kamizae is a 2.5..

ive even started getting a lot more info on headers ending with 2.75" collectors and when looking for a good header, its more then 1% of the market you ll find

that's cool that the big name brands are starting to realize that the collector needs to be bigger. i haven't been in the market for that stuff since i got my swap done 2yrs ago so i don't keep up on some stuff like that.
