Going Quad

[Oakley]

so then mustang has roush cat back but single pipe wither side, im trying to beef its bottom up a bit as the rectangular uk number plate makes it look a bit odd, I think im going to get a square plate and then swap the tipster quad tips to beef up its booty a bit. so the question is, do I cut black plastic to make enough room for the quad pipes and if I do that will they sit straight? or should 100% replace the lower valance for a quad version in order to get a good look, its a 2017btw

Here’s the cleaned-up translation:

So, my Mustang has a Roush cat-back exhaust, but it only has a single pipe on each side. I’m trying to make the rear end look a bit more aggressive because the rectangular UK number plate makes it look a little odd. I think I’m going to switch to a square plate and then swap the tips for quad tips to make the rear look wider and beefier.

The question is: should I cut the black plastic rear valance to make enough room for the quad exhaust tips, and if I do that, will the tips sit straight? Or should I definitely replace the lower rear valance with a proper quad-tip version to get a clean look?
It’s a 2017, by the way.

In plain terms:

He has a 2017 Mustang with a Roush cat-back exhaust, currently single exit per side. He wants the rear to look more muscular, probably by using quad exhaust tips and a square UK plate. He’s asking whether he can just trim the existing rear diffuser/valance, or whether he should buy a proper quad-tip rear valance so the exhaust sits correctly and looks OEM/clean.

It came with the car, mine is a Mach 1. Ford Performance sells essentially our rear for other models though.

I have this kit from ford installed on my 21 GT with a Roush X pipe. I absolutely love the way it sounds and it looks bad ass too.

cool @Fordphanatic have you gone 2.5 - 4" there? Im going over 2.5-3" as was nervous of fitment here's the current setup and what ive ordered so will hopefully look like when its on

its not a huge difference and now ive put them up side by side like that im not even sure its enough to warrant the change... god dam it
