Questions DC Sports for GT-S

Hi guys, one question!! Can I have problem with DC Sports header for my 2002 Celica GTS Restyle!?!?

The DC Sports fits: Toyota Celica GTS 8/99-3/03 (W/O Air Injection)...Can I have problem with flange or air injection tube???

If your car has air injection then you will have problems. If it doesn't have air injection then you can get it. Be aware though that the DC Sports header does not do anything for the 2ZZ unless your port and polish the head.

see i always wondered about people adding a header and catback to their car. the only difference i think it would make is the backpressure of the exhaust. the header i do not think would do anything in general without a midpipe.

It wont do anything if you port and polish the head either. The DC sports header primary tubes are smaller than the ports on the flange so it limits flow. Go with something else other than the DC sports since it is just a copy of the stock header anyway. You'd be better off porting your stock header.

Ah so that was the problem. I was always under the impression that the runners were too big and slowed down flow. At least that seemed to be the information managed around here.

The only people who benefitted from the DC header were mechanics, customs officers, aem and of course scrap metal merchants.

Now I heard that to put a header on your car you need to upgrade the ECU? is that true even with a GT-S ?

What kind of gain will you see with a upgraded ECU as to the stock one?

I have a manual gt with an injen intake and dc sports header. I love it, there were no gains with just an intake so I got the header for a really good deal and went with it. There are better ones than a dc though, but my car stock was like 8.9 0-60 I think, now with the the intake and header im down to 7.7. To bad that's still slow.

I see a question about the dc header like every other week
