Fixing My Exhaust Tip Issue

[mtX5]

so after getting my custom exhaust system, everything came out perfect except the tips; they are sticking out way too much making them look cheap (when i spent 100 a side for em ).

so now i'm in the process of getting this issue repaired and I have two options.
1. cut from the inside to bring the current tips in about an inch or two, hopefully resolving the issue
2. going with 4.6 tips (which i should have done from the beginning)


if i choose option one, i won't need to spend extra $$ on tips.

if i choose option two, it will cost a bit, but i don't mind because i can sell the old ones. (i think i am choosing option two if i can resolve the issue below)

so here is the issue, what is the best way to get these tips on? i did some searching and this seems like the best way,

but i am concerned about rusting, as well as i would prefer not to be able to see the extensions within the tips.

so is this the best way/most secure to get the 4.6 tips on?

or to avoid seeing the extensions can i custom make a bezel around the edges of the extension tips and weld the bezel to the 4.6 tips?
