Banshee Performance Industries

From a consumer’s standpoint, what do our 4.2L customers want to see developed for these cars next, performance wise?

3” Catless Downpipes for 4.2L XJR/STR…

I’m so stoked these are finally done. 🤩

-304 Stainless steel

-Auxiliary O2 b**g for wideband/EGR

Unfortunately we had to change the fl**ge design because the thick fl**ges I originally had planned created fitment issues with the stock exhaust manifolds.

We opted for an OEM style nickson spherical fl**ge to ensure proper fitment.

I’ll be installing these after this weekend hopefully after we finish moving into our new house.

Hella excited!

Once testing is done I will have these available for custom ordering. 😁
