Race header with stock exhaust...

skandal57 · 11-15-2007, 06:58 PM

Does anyone have a race header with stock exhaust video or audio clip? Im trying to keep the noise level down while making power. With and without aftermarket intake would be very helpful as well.

Caveman has that setup, It sounds really good, nice and quite untill you get on it. At WOT you get a nice tone, not loud either.
I think I have some video of his car at the track. I'll post it when I can find it.

I have BCRH, Fujita SRI and stock exhaust. Sounds very nice, but not loud at all. My friend has stock airbox/header and a BC exhaust and his car is louder than mine.

Oh, both are 2007 FA5.

I have a dcrh with stock exhaust and k&n filter in stock air box, not to loud under 4k but after that sounds good, has a deep tone, not raspy. has slight rumble under load at lower rpms but when cruising sounds stock.

oh yeah 07 si sedan w/11k on it.

i got dcrh with 3in. midpipe(no resonator), fujita sri, and stock axle back, quiet when crusing but wot good GOD almighty sounds like a beast.......gains was good too.

thanks for this post! very informative , thanks for asking this question. I also want to keep stock exaust and get hondata reflash possibly with x's intake or a header, so this helps. I am pretty sure I am going to go with the reflash but I am still deciding what mod to go along with so this helps me keep my stock exaust, either header or intake or both...........

skandal57 · 11-15-2007, 07:25 PM

^^^WOW.. that was fast. Thank you for all the input and opinions. For me the added noise for an exhaust isnt worth the minimal power... 5-10 hp on a 3000lb+ car with driver and fuel isnt going to be very noticable. If anyone can dig up some videos, that would be great!

*for my info.. what is the output size of the DC Sport race header?

Ljineus · 11-15-2007, 07:39 PM

I'm waiting to get my dcrh header installed I've got the K&N filter in now and the P2R gaskets and throttle body spacer on it, but I'm really anxious to see what it sounds like with the header on. Any sound clips with this setup out ther?

***Sirbelch*** · 11-15-2007, 07:54 PM

I read somewhere that hondata made the reflash with a DCRH and a stock exhaust.

skandal57 · 11-15-2007, 08:05 PM

The reflash is suppose to work with an intake or header or both.. the exhaust the way hondata puts it (as long as its LESS restrictive then stock) leads me to believe there isnt a whole lot of power to be made there. I eventually want to do a k24 bottom end... the stock exhaust may be changed then because of the increase in displacement and airflow.

Any videos?

Exactly, I don't think putting on an aftermarket exaust is worth it, the stock setup works well with hondata....and an exaust may lose some low end.....I may just go with x's intake.......

Moonkei · 11-15-2007, 10:31 PM

I'm getting my DCRH installed tommorow (stock car) so I'll try to record a quick video over the weekend.

07 Honda SI · 11-15-2007, 10:43 PM

Yeah if i knew how i would throw some sound clips on here

ibanez37 · 11-16-2007, 10:11 AM

FWIW, when I had my RT cat on a stock car, I didn't full much gain.. then I threw on a catback and I felt some seat of the pants gains. Now, I replaced my RT cat with the DCRH and felt a LOT of gains. I think an exhaust won't yield as much, but the gains being worth the extra noise factor is the decision to make. This is unproven though, just through the butt

skandal57 · 11-16-2007, 04:39 PM

I think that a race header, cold air, and reflash will keep my company while i work on the suspension, brakes, and light track duty prep.

jumboshrimp23 · 11-16-2007, 06:36 PM

subscribed for sound clips or videos

Stealthcivic · 11-17-2007, 08:16 AM

yea, I am going with intake (probably x's intake), reflash, and possibly a header, or just intake and reflash.....

skandal57 · 11-17-2007, 06:08 PM

^alot of power is made with the race header.. i would definatly get one.
