Ok here it goes guys, bare with me now
I know nothing about performance modifications.
But I am trying to get your help on what mods I should to for the best performance gains for the buck w/o harming the engine/car. (if possible I would like to keep the car's life to a nice logetivity)

I've been researching and from what I have learned I know I will be purchasing an ecu tune but was also hoping to do an exhaust or downpipes for some gain or sound. I like the idea of downpipes because I hear they give modest gains.

My question is what would you guys recommend I do. Any brands? Will it give me error codes? Anything I should know about considering my position? What do I need to do exactly? I dont know anything about catalystic converters or what catless means or any of that stuff so any input would be appreciated

Thanks

If Engine life is your biggest concern than don't tune or modify it. Any mod or tune will cause the engine to wear faster than a car running at stock boost levels.

Your about to get rapped by people on this forum because you didn't search.

Basically a few options for ecu tune: procede, Cobb, jb4 and active.

I listed those from best to last in the order I would run on my 335.

Currently running procede v4

Good luck

Tunes: JB4, Procede v5, Cobb AP, Active Autowerke, ect, ect.

Downpipes : AR Design 3'' N54 Downpipes (Catless), Active Autowerke N54 3'' Catless Downpipes, CP-E downpipes, ect

Front Mount Intercoolers: Helix Stepped FMIC, HPF FMIC, Big Tom FMIC, AMS FMIC, Spearco FMIC, CPE FMIC with built in oil cooler, and many others.

Intakes: aFE Dual Cone Cold Air Intake, BMS DCI, Many other DCI's...just google 335i DCI, Dinan, Injen, ect.

Exhaust: HPF, Borla, Supersprint, AMS, Racing Dynamics, (just search! )

If you worried about longevity I would just get basic mods done like Intake, Exhaust, and running a mild tune that only increases boost by a few PSI like JB+.

downpipes arent bad for cars longetivity are they?
Yes I ve been searching and I found that AR designs catless are the most popular. Ive also heard making them "catless" gives you error codes sometimes. Is this true? Do I need to do anything about it?
Thanks for the help

I would do tune first, then DPs..

For DPs ar design is considered the best, and the new AA pipes have been shown to be popular as well. There is a GB on the AA pipes right now
