Can I modify a 15-18 Tahoe exhaust to fit a RCSB 2018?

[BigTopGT]

Picking up a 2018 Z71 RCSB in a few days and I'm going to upgrade the exhaust. 

 

I found an aftermarket exhaust for a 15-18 Tahoe for a song, but since mine is a 2 door short bed silverado, I'm wondering if it's as simple as cutting, shortening, and rewelding it to accommodate for the shorter truck length. 

 

If anyone has experience, I'd appreciate it a bunch 

 

Thanks! 

 

Edit: I misread the initial ad and it's a Tahoe, not a 4 door silverado.

I’ve always used a bender. He started when I moved to Texas in 1979 and sold his shop a year ago. He’s done all mine and my family’s. I always wondered why everyone didn’t use a bender. My first venture into exhaust was my 1968 fastback impala. I went to a parts store and bought the dual side and two glass packs. It was a royal pain. Took all of two days. Luckily for me I had auto shop in school and finished it there on a lift. I’ve used a bender ever since. To your question. It comes down to the straight pieces. If it was me I’d take it to a bender change the muffler and forget about it. Of course after that the annoying V-4 sound will make itself known. You’ll be looking to shut that off. I used a hand held tuner.

It sounds like maybe it's going to be either more trouble than it's worth or it'll 3nd up costing me the same as buying the right exhaust in the first place.
