Exhaust Tips

[SKStinger]

Yes. Some people may not care at all but I like to optimize every little aspect and this bothers me a little bit.

But how do you know it’s “optimized”? Maybe that tiny restriction increases back pressure a teeny bit and you add 1hp?

Pretty sure they are in this thread or my album.

But here you go.

It really is more matte than gloss... but the pics make it appear glossier than it is.

what center caps did you use?

what center caps did you use?

Used the “e” 18” center caps. Put the k logo over.

since then, I’ve gone to a Kia center cap.

I just hate the 5 spoke monstrosity that the oem 19” have.

Anyways, keeping fingers crossed aftermarket sway bars will be a lot more easier to install. Wish me luck!

Well, the front sway bar is easy......

It's funny how we got to "optimized exhaust tips", yet we all know they are only for the looks and nothing more. Hint, look at Mazdaspeed 6 and Lexus IS F. All had fake plastic looking exhaust tips.

The front is done. Whiteline is being total ass... seriously they are sending one piece to me at a time. What a crappy joke that is... Waiting on a last piece to arrive as a rear sway bar.

Has anyone already, or can someone provide me with a decent step by step guide to trim the diffuser for round tips?

Not really a guide but if you are getting large round tips 89MM outlet carbon fiber ones like these you'll need to trim a bit from the top and bottom. Best thing to do is see how they fit and trim a little a time with a Dremel. I went overboard and ended up not using round tips because they still made contact with the diffuser and caused vibrations. The red shows where I had to trim with a different exhaust that's shown, and it will be different for everyone anyways.




You could also get a smaller outlet like 76MM and not have to trim the diffuser at all. Doesn't look all that good imo though.

This is why I recommend the oval tips. They don’t require any trimming so they don’t rub on any part of the diffuser. They are also about the same outlet diameter as stock so look good.

I’m about to do the install this week on the 89mm round tips.. the only thing I’m actually worried about is the vibrations and the impact it can have on the car. And also if these tips heat up the surrounding area enough to melt/warp paint.
im probably just being too hesitant haha

When I had the 89MM rounds installed on the MBRP, even with the trimming of the diffuser they were still wedged in there. Taking a look at the back of the vehicle on startup, the exhaust tips do not move but the bumper sure did. At certain RPMs the vibrations made it seem like I had an aftermarket subwoofer slapping in the hatch. It made for a noisy (too much for me anyways) cabin.

I would say try it anyways, you may have a better experience than I did. I liked how the larger round looked more than the ovals. Also if you are getting the faux carbon fiber 89MM rounds you don't have to worry about heating/melting.

I have the 89mm tips, trimmed the holes and while there is still some contact, I don't get any noise at all. I've had the exhaust since the beginning of Feb.

you dont get any rattle and cant feel any vibrations?

 

[Koreandude]

Correct. No vibrations, no 'rattles' of any sort. If there is, perhaps those people need to trim more. While there is some touching/rubbing, it's very minimal, nothing enough to cause noise in my opinion.

 

[evoMR]

for those that had their tips welded on, do you guys have pics of the final end product?

TIA!

Why do you want to weld them on? That would mean that you would have to cut your exhaust in order to remove it. The clamps work just fine as long as you tighten them well enough. I've ran 3 sets of tips now and haven't had a single one loosen up on me.

Has anyone added tips to the Ark exhaust? I plan on doing the oval tips. 63mm / 105mm?
