Compare DC Sports EX-1012B, Borla 20156 and MagnaFlow 35121 by dimensions, mounting and sound limits before choosing an exhaust tip.

If you are shopping for an exhaust tip for a deeper sound, the DC Sports EX-1012B is the resonated option to investigate first. The Borla 20156 is a compact clamp-on choice, while MagnaFlow 35121 suits a planned weld-on installation. None has a verified sound comparison here that establishes a deeper note on your vehicle.

We selected these three by documented construction, dimensions and attachment method. We have not installed them or measured their sound. Buy a tip only if its fit and appearance make sense even without an audible change; a sound problem deserves advice about the complete vehicle-specific exhaust system.

Best exhaust tips: three useful options

Tip Inlet / outlet / overall length Attachment Best reason to consider it
DC Sports EX-1012B, black 2.25 in / 3.75 in / 9 in Bolt-on; confirm accepted tailpipe range Resonated construction
Borla 20156, polished 2.5 in / 4 in / 6.25 in Clamp-on; clamp included Shorter polished clamp-on option
MagnaFlow 35121, polished 2.25 in inside inlet / 4 in outlet / 7 in Weld-on; one tip Double-wall, non-resonated finish

These are tip dimensions, not a vehicle fitment list. In particular, an inlet dimension does not establish the range a bolt-on mechanism can safely grip. Measure the outside diameter and usable straight length of the existing tailpipe, then confirm the exact connection with the manufacturer or installer.

1. DC Sports EX-1012B: the resonated choice

DC Sports identifies EX-1012B as a black powder-coated stainless-steel resonated tip with a 2.25-inch inlet and 3.75-inch outlet. Its current Amazon item specifications give a nine-inch length. It is the relevant choice here if resonated construction is your priority, although that label alone does not establish a deeper, louder or drone-free result.

This is a bolt-on tip. The current manufacturer page does not establish a complete accepted tailpipe-diameter range, so confirm that range before buying. Do not assume that the 2.25-inch inlet fits a 2.25-inch pipe. Leave room for the full nine-inch body and for the attachment hardware.

Check DC Sports EX-1012B specifications. The matched Amazon listing identifies EX-1012B, UPC 757558509331 and a unit count of one. Select this black tip rather than a similarly named EX-1011 or a different-size variation.

2. Borla 20156: a compact clamp-on option

Borla 20156 combines a 2.5-inch inlet, four-inch round outlet and 6.25-inch overall length. It uses polished T-304 stainless steel with an angled, rolled-edge outlet; Borla lists the clamp as included. This is the shortest tip in this comparison, making it worth checking when a nine-inch accessory would occupy too much space.

Choose it for the finish, length and clamp-on mounting. Borla describes this specific tip as lined; we have not treated that as a tested acoustic benefit or a promise to deepen the exhaust note. Confirm that its inlet and clamp suit your tailpipe, and that the four-inch outlet clears the bumper opening.

Check Borla 20156 and its included clamp. Compare part number 20156 exactly: other Borla tips have different inlet sizes and mounting methods.

3. MagnaFlow 35121: for a weld-on installation

MagnaFlow 35121 has a 2.25-inch inside inlet, four-inch round outlet and seven-inch length. The polished stainless-steel tip has double walls, a folded edge and an angle-cut outlet. MagnaFlow explicitly marks it as non-resonated and weld-on, with a quantity of one.

It makes sense when an exhaust shop is already planning a compatible welded connection and you want this shape. Include installation in the total cost. Its double-wall construction is not evidence of a deeper sound, and a universal catalog label is not confirmation that it fits your vehicle.

Check MagnaFlow 35121 dimensions. Have the installer approve the inlet, available length and outlet placement before ordering; do not buy it expecting the included clamp of the Borla option.

How to buy the right size

Start with a cold exhaust and measure the actual pipe, not a decorative factory surround. Record its outside diameter, straight mounting length and the space around the exit. A caliper can help with diameter; photographs and those measurements give the manufacturer or installer something specific to check.

Check the tip’s full length and largest diameter against the bumper, nearby trim, bodywork and ground clearance. The chosen mounting position must also leave room for the hardware and normal exhaust movement. Follow the vehicle and exhaust manufacturer’s clearance instructions; this comparison does not supply a universal safe gap or tightening torque.

Decide whether you want a removable clamped connection or a welded installation. The Borla includes its clamp, DC Sports specifies bolt-on mounting, and MagnaFlow 35121 requires welding. Use the instructions for the exact part, and have a qualified exhaust shop handle a fit that needs fabrication.

What to expect from the sound

The evidence here supports choosing among tip designs, not ranking how deep they sound. MagnaFlow’s muffler guide explains that muffler body size and inlet/outlet configuration affect loudness. If your real goal is a different exhaust note, discuss an appropriate vehicle-specific solution with an exhaust specialist before spending on a tip alone.

Keep emissions equipment, heat shields and required sound-control equipment intact. Check the rules that apply where the vehicle will be used, and ask the installer to confirm that the finished exhaust exits safely. A tip should not be used to cover up a leaking, damaged or insecure exhaust.

Frequently asked questions

Will a resonated tip definitely make the exhaust deeper?

No such guarantee is supported by this comparison. EX-1012B is identified as resonated, but we do not have controlled measurements for your vehicle. Choose it only after the fit is confirmed and its design meets your needs.

Does a four-inch outlet fit a four-inch tailpipe?

The connection is governed by the inlet and mounting design. Both Borla 20156 and MagnaFlow 35121 have four-inch outlets, but their listed inlets are 2.5 and 2.25 inches respectively. Outlet size also matters for bumper clearance.

Are these sold as matching pairs?

Do not assume that. The matched DC Sports listing shows one unit, and MagnaFlow lists one tip. Borla 20156 is an individual tip with a clamp. If your exhaust needs two, confirm quantity and compatibility for both sides before ordering.
