Granatelli 3" Oval Exhaust Tubing, 45° Horizontal Bend, Stainless – 313536

More Clearance. Smarter Exhaust Routing.

Traditional round exhaust tubing can become a major clearance problem on lowered cars, air-ride builds, hot rods and custom chassis. Granatelli's 3-inch oval exhaust tubing provides a lower-profile alternative that allows builders to maintain a large exhaust path while making better use of limited space underneath the vehicle.

Designed for Low-Clearance Builds

The oval profile measures approximately 2.2" x 3.45" O.D., allowing the tubing to sit lower against the vehicle than conventional round 3-inch tubing. Granatelli designed this oval exhaust system to help builders gain valuable clearance in areas where conventional exhaust tubing can hang too low.

The 313536 horizontal 45° bend is especially useful when the exhaust needs to change direction around chassis components, fuel tanks, crossmembers or other underbody obstacles.

3" Stainless Steel Exhaust Pipe, Oval Profile

This is 304 stainless steel exhaust pipe tube with 16 gauge (.060") wall, formed into a 3" oval so it carries a 3-inch exhaust path in a flatter shape. If you have been looking at rectangular or flat exhaust pipe to gain clearance, oval tubing is the practical way to get there: it bends, welds and joins to round pipe with purpose-built adapters, and it can gain roughly three-quarters of an inch of ground clearance over round 3" tubing, depending on the install.

Custom Exhaust Tubing That Works Together

• 313535 straight 3" oval tubing, 5 ft for the long runs
• 313537 90° horizontal, 313538 45° vertical and 313539 90° vertical bends to finish the route
• 313531 round-to-oval weld-in adapter, plus V-band and 3-bolt flange versions, to tie into round headers, mufflers or a cutout
• 313541 polished stainless oval muffler and 313540 oval 45° turndown

Technical Specifications

Build a Complete Oval Exhaust System

The 313536 is part of Granatelli Motor Sports' 3-inch oval exhaust tubing family. Combine horizontal and vertical bends, straight sections, adapters, mufflers and other oval components to create a custom exhaust system designed around your vehicle's available space.

Because oval bends are designed for specific routing directions, careful planning of the exhaust layout allows each component to work together for clean, efficient routing through tight areas.

3" Oval Exhaust Pipe FAQ

Horizontal or vertical bend?
The 313536 horizontal bend changes direction side to side, around a fuel tank or crossmember. Use the 313538 45° vertical bend to step the pipe up or down.

Will it connect to my round 3" exhaust?
Yes, through a round-to-oval adapter. Choose weld-in, V-band or 3-bolt flange depending on whether you want the joint serviceable.

What material and wall thickness?
304 stainless steel, 16 gauge (.060") wall, with a 4.50" centerline radius.

How much clearance will I gain?
About 0.75" compared with comparable round 3" tubing, depending on how the system is installed. See it in a real build: Building a C10 Oval Exhaust With Granatelli Motor Sports Tubing.

Route It Right. Keep It Low.

When exhaust clearance matters, the Granatelli 313536 3-inch oval horizontal 45° bend gives you the flexibility to route your exhaust where conventional round tubing cannot.
