PE mod difficulty

Hey guys, so I bought a PE modded muffler and wanted to install it myself... How hard is the cutting and welding process on the exhaust? Any extra hardware required at all? I've never cut an exhaust before but i'm sure it can't be that difficult, just take measurements, cut and weld right? If anyone has any advice or anything please comment! Thanks so much.

You seem to have already have a good understanding of the process...what exactly is the problem?

Just bring it to a shop if you have to ask how to do this...or like you tube it, or stand outside of an exhaust shop for 5 minutes...

Do you recommend clamping it over welding it on? I understand it'll be better for ease of access but will it be secure?

Clamps work fine. Mine has the bmw clamps. But at the cost of them bmw clamps you should have it welded especially if you don't plan on removing it. Or use generic clamps which I am sure work fine. If you do then use clamps than keep your stock mufflers otherwise have it welded on.

I am keeping my stock muffler... Now would the exhaust just clamp using and ordinary U-clamp. After looking up videos it just doesn't look like the U-clamp will hold the muffler and the midpipe together. I may be wrong, and gotta see it in person. i'm sorry if i come off as misunderstanding lol. I'm coming from a 350z to a 335i. That car was much different to work on.

I also came from nissans. No a u joint probably will not work. It may. Bmw makes claps for this specifically at 20 bucks a pop. So I would weld it. But if you ever want to go back to stock buy the bmw clamps. ECS sells them.

There are two dimpled marks on the exhaust where you are suppose to cut it in between, doesn't have to be perfect but try your best. I believe that's how they come when you order an exhaust from BMW. Then purchase the clamps and you're good to go. Been running my exhaust like this for years and everything is perfect with no leaks. I would never consider welding it, this is way too convenient if you have to drop it.

If you aren't sure about a mod of this difficulty, then do it anyway. Clearly you're interested, the worst outcome is you cut your fingers off. The second worst outcome, is you pay someone to fix your mess.

All joking aside, shouldn't be a real tough one, and looks like a fun mod to do if you aren't interested in buying a full exhaust. Modding is half the fun.

You're totally right, luckily I have all the resources to do the work. I may just do all the cutting and measuring myself and have one of my buddies weld it in.
