Headers will give you the best performance gain, and they used to be somewhat available, but for older Z3's they are very hard to find a good set of prefabricated stainless steel headers. Adding a port and polish to current headers may be an option towiden the headers slightly to make the header gasket which are generally larger than the exhaust port size in the headers. For reasonable priced "back boxes" of mufflers that will help with a freer flowing exhaust check out Megan Racing. They sell free flowing "racing" mufflers that are not crazy loud that may get you into trouble. It would be one of their "Universal" mufflers, and would need to be welded onto current exhaust but they are stainless and not too expensive.
Generally, the Horsepower gain with a better exhaust is small somewhere say 10-20 HP unless you include new Headers which may give you another 10 HP over the exhaust gain.. But where you will see an improvement is your throttle repsonse, it will be much quicker. The majority of cars today and Z3's or E36's included is by restricting air in, and air out to "reduce" horsepower and in return get better MPG for whatever pollution laws your country may have. Most countries today regulate certainly MPG in cars, and it's always air intake and exhaust where companies "detune" a car today. It's just anything else, the price for a good exhaust has gone up a good bit making exhaust systems expensive for nice ones.
LHD gang hahaha, i am hopefully getting an exhaust tomorrow either custom backbox setup or straight up backbox delete. Don’t want to do headers due to Smog/emissions issues with cat deletes.
Awesome! Let us know how it goes 🎉 yeah that's the sad thing with exhaust mods, the harsher and harsher emissions restrictions. Unless it's a race car 😉
@@FeelTheDrive hahah had that on my 128 back in the day, catless headers into 3” straight pipe. Too old for that rasp now. Still Need to do subframe reinforcement, apparently no one wants to touch it lol
I’m buying an s50b30 off a relative for $750 and I already have a zf transmission ready to go. Any opinions on if I should keep my m44 or mo powa babeh? Obviously I’m first doing all the bushing and chassis upgrades first.
I have the same engine and currently investigating a custom Cat Back...forums indicate this could be around the 500 quid mark...I'm awaiting a quote from Portsmouth Powerflow so will let you know
Hey would my z3 2.3 m52TU benefit with the exhaust system from m54 z3s. Midpipe all the way back. Since it is dual piping. Because I had a e36 323is and a common mod was doing the 328/m3 exhaust swap. I wondered if it's similar with z3s

Really liking the Z3 beginners guide videos!
Thanks for watching them! We hope it's helped

Why do you have a striper pole ?
@@244hz-Noice traded a paperclip for it
I have a z3 2.5 m52 with just a muffler delete and it sounds great and even better it passes smog in California
Hey man, any drone? I usually drive with my top down here in nyc, but im trying to figure out if itll be too annoying
@@Inyourface-yj8wo honestly yes a little but you get used to it and it’s not so bad if you don’t rev it all the time
did you do the Rear or "mid" one?

I have z3 with 1.9 M44, recently got Cobra cat back, hoping to install next weekend weather permitting. Will feedback on any changes.
One of the best Z3s! Hopefully it'll help other people who are still deciding

any feedback on this? Im looking to buy the cobra cat back and looking for someones opinion!
