4th times a charm. RKP Diffuser

CJ_M4 · 09-16-2021, 06:52 PM

After trying 3 diffusers

1) eBay performance replica- fitment about 7/10
2) painted performance replica - fitment 8 or 9/10
3) Higher cost vendor performance replica(didn't try on due to clear coat issues and returned)

I've gone with the RKP diffuser with 1x1 weave. Fitment is great and looks good with the new exhaust tips.

Thumbs up for RKP.

Excuse the dirty car.

I think, could be wrong, Germany or USA. Didn't check on the back in the install.

More pix! Does this come down enough to somewhat hid the ugly muffler?

Take a couple hours out of the weekend to paint the muffler. It makes all the difference in the world.

Not quite. about the same, maybe slightly lower but not really.

OP - RKP is typically 2x2 to match MP. I think they do offer 1x1 in some products.

Depends on the angle. I have the same RKP in 2x2 and it doesn't bother me.
