American Racing Headers C7 Corvette Headers

American Racing Headers C7 Corvette headers are available with options that allow you to fine-tune your exhaust system to match your upgrades. ARH C7 systems set the bar for quality, performance, fit, and ease of installation. Options include a variety of primary sizes and your choice of X-pipe midsection diameters, ARH's exclusive X-pipe forward location (on select models), and severe-duty cats.

They will surpass your expectations in quality and performance. Additional features of American Racing Headers C7 Corvette headers include: * 100 percent long-lasting 304 stainless steel * 3/8 in. thick laser-cut flanges for a warp-free seal * Hand-ported TIG-welded inlets * Optimized primary tube routing for superior fit and performance * Merge collectors include welded scavenger spikes * Catted systems feature 200 cell metallic substrate catalytic converters for extreme durability * The only set of headers you'll ever need to buy * All American Racing Headers exhaust systems are for off-road use only

The result is an aggressive custom sound and improved power. Order the pipes recommended for your vehicle. Additional notes: * Built from premium T-304 stainless steel, superior to T-400 Series (such as 409), to give you the absolute best in performance and durability. * Ultra-smooth mandrel bends ensure maximum flow and power; and precision computer numerical control (CNC) manufacturing ensures an accurate fit * Installation requires cutting the driver's side OE tailpipe assembly. OE tailpipes are resonance-free pipes and are reused with the Borla 60717. Use OE tips or optional Borla tips to complete the system.

Dinan Valved Exhaust Systems

Dinan valved exhaust systems are available in cat-back and rear axle back options for a variety of Toyota applications. These exhausts convey the sweet sounds of a deep, rich, euphonious note that are unmistakably Dinan; in addition to retaining the flexibility of valves, Dinan exhausts are the epitome of sound without sacrifice. Utilizing factory cut points and mounting mechanics, Dinan exhaust systems are a straightforward install with precision fitment, just like you'd expect straight from the manufacturer. Mounting and proper fitment is where the similarities to the factory exhaust end, however. Fabricated from brushed 100 percent T304 stainless steel, TIG-welded and free of hydroformed pipe, each upgraded system is a marked improvement from its predecessor—both in terms of material/construction and overall looks. For weight savings and simplicity, the stock single-to-dual pipe setup has been abandoned in favor of an enlarged, free-flowing single pipe system. This pathway feeds into a muffler that limits frequencies associated with drone, as well as assists in altering the overall tone of the setup to deliver the signature low Dinan rumble. The no-nonsense design allows shocking versatility in sound levels when paired with features, like valves, often associated with more fanciful alternatives. The unabashedly spartan, yet effective, pipe layout forces gasses to escape from the rear out of massive dual, straight cut, 114.3mm (4.5 in.) exhaust tips emblazoned with the laser-engraved Dinan logo. The tip branding further cements any lingering doubt that the system visible is something above and beyond stock. Unquestionable enhancements to the overall chorus emitted through the Dinan system transcend all modes, making the vehicle a delight to drive and enjoy. However, for those who want options to limit the extraordinary soundtrack for late night or early morning arrivals/departures (or any number of other reasons), factory valve control is retained. This effectively makes the system behave similarly to a straight-pipe system that promotes maximum flow and volume when the valve is open—and emit more subdued resonant vocals when the valve is closed; and exhaust gases are wholly redirected through the muffler. It's the perfect blend of civility when not pushing the car or the full spectrum of auditory delight when in it. No matter the situation, Dinan valved exhaust systems are the answer for discerning enthusiasts looking for sound without sacrifice. Additional product features: * Maximum gains of +6 HP and +5 lbs.-ft. of torque * Enjoyably louder, sportier sound * Drone abatement technologies used to reduce cabin resonance * Dual 4.5 in. (114.3mm) double-walled clamp-on tips with laser-engraved Dinan logo * Larger diameter piping for increased flow (83mm throughout primary run vs. 80mm at largest point) * 100 percent 304 stainless steel construction * Retains factory valve control * Factory-like fitment with included mounting hardware * Tips available with polished or black ceramic coated finish
