Match your Gas Gas to a kit

Gas Gas names its models by letter code and engine size, and the table reads the same way. The 450F got new listings from 2024, so look at your bike's year before you choose.

Two kit formats across the Gas Gas range

On the MC, EC, EX and EW models, GPR sells the Pentacross as a full system: header pipe and silencer (muffler) come together in one kit. You pick the build, Full Titanium or Inox (stainless steel). The EC 500 F is the exception, listed in Inox only.

Both 700s, the E and the SM, use slip-ons, which keep the stock header and swap the end can. They get the same four lines: Albus Evo4, Furore Evo4 Nero, Furore-X Inox and Grand Prix Evo Titanium.

Questions Gas Gas riders ask us

Pentacross Full Titanium or Pentacross Inox: what changes?

The material. It's the same Pentacross full system, built in titanium throughout on one version and in Inox, GPR's stainless steel, on the other. Both are listed for the MC, EC, EX and EW, with the EC 500 F in Inox only.

My MC 450F is a 2024. Does the 2021 listing fit?

No. GPR splits the 450F by year: one set of listings from 2021 and a newer set from 2024. The MC, EC and EX 450F are split that way, so open the listing that starts at your bike's year group.

Can I get a slip-on for an EC or an MC?

Not in this range. GPR lists full systems only for the MC, EC, EX and EW. This page's slip-ons fit the E 700 and the SM 700 only.

Is there a separate kit for the MC 450F Factory Edition?

Yes. The 2023 Factory Edition has its own Pentacross listings, one in Full Titanium and one in Inox. Use those rather than the standard MC 450F ones.

Is the E 700 slip-on the same listing as the SM 700 one?

No. The lines match, four of them, yet GPR lists the two bikes apart. Check that the title says E 700 or SM 700, whichever you ride.

Which kits are listed for the EW 500F?

Pentacross full systems from 2024, in Full Titanium and in Inox. The EC 500 F of the same year has the Inox version.

The dual Shorty voodoo exhaust looks extremely

The dual Shorty voodoo exhaust looks extremely well on my Hayabusa. It does not give an engine code and was sent to me very fast. Customer service was great very pleased with this product. To me, it is one of the best looking exhaust systems for the Hayabusa. It is exactly the way I wanted my exhaust to look.
