Production should take 3-4 weeks from date of ordering. 

Here we have my Version 1 of the rear diffuser for the 2015-2021 & may fit newer Subaru Wrx/Sti models.

Now what sets me apart from everyone else? I'll let you be the judge of that.

Both side spats and diffuser come with multiple mounting points for added rigidity. It is HEAVILY suggested that you use blue lock tight on all hardware. NOT RED. Also it is highly suggested you have a professional install it.

This diffuser is also upgradable in the future if you like. What does that mean? The fins can all be removed and others can be ordered for it. No longer like that style Swap them out! How cool is that?

My logo will be added to one fin on the diffuser and one fin on the spat. 

Also another option that I offer is a base coat Zinc Epoxy Primer. What this is is a coating that helps with corrosion. If you are using it in the winter months with all that terrible salt on the roads, This WILL NOT eliminate the potential but it will definitely help and add another layer of corrosion protection.


All items are made from a high grade aluminium with excellent corrosion properties. Failure to keep them clean and taken care of can lead to issues down the road.

All hardware is stainless, YES STAINLESS, not that zinc coated steel stuff. Again added corrosion protection. Oh yeah and the hardware is black to match the colour of the diffuser. No more ugly silver hardware. 

If you ever find yourself damaging your fins on the diffuser* I will offer you replacements at 30% off. Yes, you read that correct. Accidents happen and I get that. So within a year of buying the diffuser I will honour replacement fins at that percentage. Isn't that just great? 

Shipping is included in the price. Additional fees or taxes or duties is the buyers responsibility not mine.


*** May not fit stock exhaust due to mufflers. I have had customers where they made it fit it but this is at your own risk.

For custom logo the file needs to be a black and white jpg file. Not a picture of a picture or a sketch or drawing. It needs to be a physical file just like a file a sticker company would use for cutting decals.

About Powder Coat 

The powdercoaters (yes, I outsource theses) do their best when coating these pieces. Little minor flaws or imperfections may be seen in the powder. Large flaws will not pass my quality control and I will not ship pieces with them. Please understand this. If you want absolute perfection in the powder choose to have them in bare metal and have your own powdercoater do them so you are completely happy.
