Oval Exhaust Tubing FAQ

Oval tubing can provide more clearance beneath a lowered vehicle while offering an alternative cross-section for exhaust routing. Check dimensions and required flow for your build.

Granatelli's 3-inch oval tubing is designed to offer roughly three-quarters of an inch of additional clearance compared with comparable round tubing, depending on installation.

The referenced Granatelli 3-inch oval tubing has an approximate 2.2-inch by 3.45-inch outside profile. Verify the current product dimensions before designing brackets or cutouts.

No. Oval tubing has distinct width and height dimensions, so nominal 3-inch size does not mean a 3-inch circular outside profile.

Granatelli's 3-inch oval tubing is one option to evaluate when vertical clearance is limited. Compare its 2.2-inch by 3.45-inch approximate profile with your available space.

It may improve packaging and ground clearance under a lowered Mustang, subject to chassis, suspension and exhaust layout. Measure the available space before ordering.

Yes. Check the product catalog for available lengths, material and current dimensions of the 3-inch oval tubing. See the oval exhaust components.

Granatelli part number 313535 is listed for a five-foot section of 3-inch oval exhaust tubing. Check the current product listing for exact dimensions and packaging.

Yes. Select 45-degree and 90-degree oval bends are available; verify their part numbers and bend geometry before planning the exhaust route.

Granatelli part number 313538 is listed as a 3-inch oval 45-degree bend. Confirm current dimensions, material and availability on the product page before ordering.

Granatelli part number 313539 is listed as a 3-inch oval 90-degree bend. Verify the current bend geometry and material against your fabrication plan.

Yes. Granatelli offers 3-inch oval-to-round transition components; verify the specific part number, direction and connection dimensions for your exhaust.

Granatelli part number 313531 is associated with the oval transition adapter family. Confirm the exact connection direction and end sizes on the specific listing.

Plan the straight oval length, bends, round-to-oval transitions, compatible cutout if desired and suitable hangers. Verify dimensions and stock for every part number. Start with the Granatelli Motor Sports oval exhaust collection.

A purpose-built round-to-oval transition is typically required. Check the nominal sizes and connection dimensions before welding.

Usually not. Routing and joining oval sections often require compatible transitions and custom fabrication.

Use a correctly sized oval-to-round transition and verify the muffler inlet outside or inside diameter. Have the assembly aligned before welding.

Measure the oval profile and the round end's actual inside and outside diameters, along with material and available insertion or welding length.

Not automatically. Most standard round clamps do not fit oval sections; use joining hardware specified for the actual profile.

Yes, if the cutout and tube dimensions and joining method are compatible. Compare both specific product listings before fabrication. See our oval exhaust cutouts.

Check motor housing, wiring, valve travel and hot exhaust outlet clearance at full suspension movement. The tube's low profile does not guarantee actuator clearance. More cutout answers are in the Exhaust Cutout FAQ.

A suitable bung can be installed by a qualified fabricator if it seals and positions the sensor correctly. Preserve the factory emissions-system configuration and required sensor location.

Potentially, if the system's temperature, flow, packaging and material requirements are satisfied. A fabricator should verify transitions and clearance for the build.

Measure floor clearance, exhaust tunnel width, suspension travel, hanger locations and the outside dimensions of the tubing and transitions.

That orientation is commonly used for ground clearance, but the correct placement depends on chassis space, weld access and component clearances. Follow the part's installation requirements.

Not necessarily. Orient the tube to meet the required ground, drivetrain and body clearances while using compatible bends and transition geometry.

The orientation may be adjustable in a custom fabricated installation if both ends align and clearance remains adequate. Test fit the complete assembly before welding.

Locate the transition where the entire assembly, including its wider or taller end and welds, clears the road and chassis through suspension travel.

Yes. Verify clearance through suspension compression, droop and axle movement, not only at static ride height. Keep the exhaust away from brake lines and moving suspension parts.

No. Preserve suitable heat and vibration clearance from the floor, fuel lines and wiring. Use supported exhaust routing rather than relying on contact with the body.

Yes. Leave sufficient movement and clearance so heated tubing does not contact the floor, driveshaft, brake lines or suspension. Use appropriate hangers and flexible connections.

Temporarily mock up each tube and bend with the car safely supported at representative suspension positions. Measure to the floor, drivetrain, chassis and service-access points.

Yes, where the material, dimensions and welding procedure match your exhaust design. Use qualified fabrication practices and check for leaks after installation.

Use appropriate fixturing, controlled heat input and a welding method suitable for the tubing material. A qualified fabricator should inspect the finished joint for fit and leaks.

Yes. Mark bend direction and centerline orientation, then tack fit the entire route and verify ground, driveshaft and chassis clearance before final welds.

Poorly formed or overheated seams can leak or crack. Inspect all altered joints and perform a suitable exhaust leak check before use.

Uncontrolled flattening can alter wall thickness and flow area or create weak seams. Use a correctly sized manufactured transition where practical.

Material compatibility, welding process and thermal expansion must be considered. Match the transition and filler materials appropriately and consult a qualified exhaust fabricator.

No. Use suitable hangers and supports that allow for exhaust movement and thermal expansion.

Use appropriately located exhaust hangers and flexible allowances for thermal expansion and drivetrain movement. Do not suspend a long section only from its end connections.
