To boost your HP as well as total Corvette efficiency, it's all about air flow - particularly, how much cool air streams into your engine's burning chamber. Southern Automobile Components is the place to go with your next engine upgrade. Our C5 Corvette headers use optimum air circulation, better HP, premium torque and also even more - if you want better Vette efficiency, SCP has all the C5 Corvette headers available you need. C5 Corvette headers from Southern Vehicle Components are made by a few of the most revered suppliers, and also designed for better-than-OEM performance. From the leader in late-model GM performance comes the best in C5 header technology. The product of months of testing and also development, these long-tube headers use our patent-pending tuned-length layout to enhance exhaust scavenging for remarkable power increases. Gains of up to 35 horse power and also 47 lb.-ft. SLP's Tuned-Length Long-Tube Headers are constructed from 409 stainless steel and also attribute 1-3/4" main tubes flowing into a 3" 4-into-1 collector. They're fully suitable with all stock emissions-control equipment as well as use OEM flanges for a best fit as well as appropriate bolt retention. NOTES: Headers need SLP H-Downpipe and also Header Installment Set as well as SLP High-Flow Catalytic Converters. Not legal for use on pollution-controlled motor vehicles. Reduce 1/4-mile ETs by as much as 4 tenths of a second and increase catch rates by as long as 4 mph. Deal simple, bolt-on installment. Expense considerably less than contending C5 headers. Work with all manufacturing facility emissions equipment.
The Gen III/IV engines have the same standard requirements for the exhaust system as other automotive engines, yet these high-performance engines have details EFI system demands that must be met for the system to carry out correctly. All EFI systems call for oxygen sensing units to read the oxygen gas degrees in the exhaust as well as tell the computer if the engine is running abundant, lean, or just right. However that is not all. LS engines include catalytic converters that burn up the exhaust gases to decrease emissions. This is a very essential element to think about as well as needs a little bit of research. SHARE THIS ARTICLE: Please do not hesitate to share this article on Facebook, in Online forums, or with any Clubs you join. Many states have a classic car provision that spares older automobiles from discharges requirements and/or safety inspections, yet it is definitely important to investigate the current legislations in your state before finishing your swap. These LS7 flanges are extremely different from the traditional three-bolt flange made use of for years.
Get a reasonable area of the downpipes with the contributor LS engine to ensure you have the new-style flange.Supply Gen III/IV exhaust manifolds are fairly reliable as well as can stay up to date with 400-plus hp for many engines. The technique is finding a pair that fits your vehicle's particular framework, as electric motor places as well as engine installation usually establish exhaust manifold compatibility. One set of manifolds may fit one installation as well as not an additional. Test fitting is the only way to confirm clearances. Stock exhaust manifolds need a suitable flange that can be welded to the remainder of the exhaust system. Numerous different flanges are utilized on the supply exhaust manifolds, yet not all of them are replicated. The method here is to ensure to get a few of the stock exhaust when the engine is very first pulled from the contributor automobile. The area just below the flange is all that's needed to match the exhaust manifolds being utilized. If your engine does not have the correct flange readily available, manufacture is your only option.
Speedway Motors replicates exhaust flanges for LS1 as well as Vortec manifolds. An additional source for flanges is made use of catalytic converters. Although you can not purchasea used converter, you can get the flanges. The majority of salvage backyards gladly reduced them off as well as offer them. The supply manifolds may or may not fit your application; details on stock manifold fitment is questionable at best. Vehicle manifolds are typically too large to clear the firewall in most muscle mass cars and trucks. Supply downpipes likewise typically have catalytic converters. If they're useful, it will certainly save some money down the road. Using the exhaust gasket as a pattern, you can reduce a flange utilizing a plasma cutter. An acetylene lantern definitely reduces the steel, yet it's not the right tool for this work since it likewise warps the steel to the point where it isn't useful as an exhaust flange. Depending on the setup, there are a number of ways to reduce brand-new flanges.
