DC Sports 4-1 Header for 94-01 Acura Integra RS/LS/GS  Polished

DC Sports Integra Header - B18B1 Engine (94-01 Integra GS/LS/RS)

Your 1994-2001 Integra's got the B18B1 non-VTEC engine and you're tired of that factory cast manifold choking things up. You're looking at your engine bay and you know there's power sitting on the table that you're not getting because the stock manifold's holding you back. DC Sports makes a header that fixes that. The 4-1 equal length runner design gets exhaust out of the head faster and cleaner. You're getting horsepower. You're getting stronger midrange torque. You're getting a sharper throttle response across the whole rev range. This header's available in polished stainless steel or ceramic coated. The ceramic coating reduces under hood temperatures which helps keep things cooler during hard driving or summer traffic. You bolt it on, the Integra wakes up, and you're not turning your car into something annoying to drive every day.

Here's What The Factory Manifold's Doing Wrong

The factory cast manifold on the B18B1 is restrictive. It's designed to pass emissions testing, not make power. The runners aren't equal length. The diameter's too small. Exhaust gets backed up in there. The head's building pressure fighting to push exhaust out. That backpressure kills power and efficiency. The engine's working harder just to get the exhaust out. You're losing horsepower that could be going to the wheels. A properly designed header with larger diameter equal length runners changes everything. Exhaust scavenging improves. The head breathes better. The engine makes more power without having to work as hard.

Stainless Or Ceramic Coated - Pick What You Want

You've got two options. The polished stainless steel header looks clean in the engine bay and fights corrosion for years. The ceramic coated header does all that and it reduces under hood temperatures. Ceramic coating's thermal insulating so the heat stays in the exhaust where it belongs instead of radiating into the engine bay. You're running hard in summer traffic or you're on track and things are getting hot under there. Ceramic coating helps keep the temperature down. We've seen people run ceramic on cars they're pushing hard because it makes a real difference in how much cooler the engine bay stays. Choose based on what you're doing with the car. Street driving. Ceramic's nice but not necessary. Track days or hard driving. Ceramic's worth it.

TIG Welded And Built Right

This header's T304 stainless steel with mandrel bent runners. Every joint is hand TIG welded inside and out. That's not cheap and it's not quick but it's the right way to build a header. Mandrel bending means the pipe maintains its shape inside so exhaust flows smooth. No sharp bends that create turbulence and hot spots. Hand TIG welding means the welds are strong and consistent. You're not getting a header that's going to crack at the welds after a year of heat cycling. The CNC machined flange bolts up to your engine like it came from the factory. No weird brackets or custom fabrication. It's a direct bolt-on using your OEM components.

Real Power Gains - Not Fake Marketing Numbers

You're getting a noticeable bump in horsepower and mid-range torque. How much depends on what else you've done to the car. Stock engine. You're gaining 8-12 hp. Car's already modified with intake and tune. You're still gaining power but the numbers vary. Either way you're getting stronger throttle response and a sharper feel. The exhaust note changes too. It sounds like an Integra should sound. We've seen people put this header on expecting magic and get disappointed because they thought it was going to add 30 hp. It doesn't work that way. A header by itself adds solid gains but it's not going to turn a stock B18B1 into something it's not. Pair it with an intake, a tune, and maybe some cam work and now you're talking real power. The header's the foundation.

CARB Legal - You're Not Risking Anything

This header's CARB compliant under EO number D-370-14. You can run it in all 50 states. You're not going to fail smog testing. You're not going to have cops hassling you. You're buying a performance part that's actually legal. We've seen people buy knockoff headers to save money and then they can't pass emissions. They're stuck with a header they can't use. Don't do that. Buy the legal part.
