2007 GL-450
2007 GL 450 Mods.

Can anyone refer me to any sources for high performance modifications to the GL-450?

Examples: Header/Exhaust, ECU Mods? Etc.

Any suggestions? I did some searches and did not find any information that really applied to this specific vehicle.

Thank You,

Donald Brown

I know ECU is available - I'm pretty sure from Brabus or RennTech.

As to exhaust, I'm sure something is available but can't steer you in the right direction unfortunately.

Here's the best place for performance modifications:

Will require air freighting your vehicle to Germany, of course.

Nobody on this forum has done any substantial mods to a GL. I've been chatting with local exhaust shops, and if I end up doing anything, I'll let you know. And all the ECU flashes are impressively expensive on a $/hp gained basis. So unless you really really want it, spend your money on something else.

Yep, that is exactly why I was asking about Exhaust, usually that is good for 20-60 hp depending on the vehicle.

Thanks!
