My Ride: 330i E46
e46 330i without muffler,and 15inch rims

I have bmw 330i e46 with supersprint replika headers,k&n panel filter and remap on dyno.Two or three days ago a friend of mine told me that the stock mufler is very heavy and restrictive and i also noticed that from racing dynamics recommend changing it if you install racing camshafts,so i decided to remove it and on it's place we set two straight pipes.But now i'm not sure whether the car is faster or not...actualy i think it is slower.I'm asking for your opinion because right now i cannot afford to test it on dyno.

My other question is what brakes should i use so that i can put 15" rims on my car.I googled and found that e46 330i brakes are plug and play on any e36.Is the opposite possible or i have to use brakes from e46 with smaller engine?

thanks in advance.

1. why would you want 15" wheels on your car? lol gonna look dumb.
2. you probablly might be slower because you lost some back pressure just lopping off your exhaust...but at the same time you still have 2 res. in there so you probbaly didnt lose much. if anything you lost torque not hp

you can get under 13.88 without having 15in rims. why not get some 17in light weight rims.

You realize the OZ wheels are about 15lbs. It honestly doesn't get lighter than that. (I have the same set and size. Where were you when I wanted to buy a few more?)

Keep the OZ wheels and look elsewhere to shave time.

This is my everyday car,with navi,air cond. and so on.My idea is to put the 15" only for the drag race(one or two days),not only because they are lighter than the O.Z. but the brake disks are lighter with 6-7lb each.Can someone give me a specific answer,please.I don't care how the car would look,because i have two sets of 18" for the street.

So your going to run smaller brakes everyday or switch them every time you go to the drag strip?

Talk about a complete waste of time, maybe you should just buy a civic to crap up for the track.

That is super hardcore!!

So when you go to the dragstrip, you put on 15" wheels AND smaller rotors?

You can't just bolt on a smaller rotor. The calipers have to move too.

Stupid idea.

I dont think that the idea is stuped.I am from Bulgaria and this year we have only two drag races.The first one went well and i finished second im my class,my personal record is 13.88 with fully equipped car only without spare tire.I dont want to ruin my car by taking off the seats or any other part of the interior so im looking for other options.I dont see what would be the problem to drive with smaller brakes only for six or seven 1/4mile runs.

Good luck on trying to swap them out. You're better off taking out the seats (easier than a brake job) and running with low fuel.

Plus there's about 15 lbs of sound deadening under and behind the rear seat that could improve your time. If you don't already, take the spare out, the trunk carpet, toolset, tools, etc. If I were that dedicated and you only run two races a year I'd yank the passenger seat and the back seats for the event before I sacrificed my braking surface... just saying.

Front brakes are "downgradeable" meaning you can fit smaller calipers/rotors. there's around 6kg combined weight reduction per wheel from running smallest rotors. You can't downgrade the rear brakes unless you ruin your handbrake mechanism. Putting smaller brakes on front with larger rears could mess the brake bias among other things.

You can empty your windshield washer tank, that'll save you 5kg instantly.
