Exhaust pic and vid

Please don't beat me up too bad - it's been 3 years since I've fabricated anything and there were times I did take the short cut and made do with what I had even if it wasn't optimum.

Also I finally figured out what the phrase "make do" means. It means you will actually make doo doo, as in poop, if you don't do things the right way. This exhaust won't win any awards, but for tha past few days laying on my back I think I did pretty good all things considering.

Forgot about this one...

Do you have more pictures of the exhaust cutouts and actuators?? They look fairly small compared to what I normally see. I will be changing the cheap 3" system out on my y34 eventually and will do a similar dual magnaflow like my y33 had, but really want to do cutouts this time.

Things sounds MEAN!!!!

They are both 2.5" but technically they are smaller than that since the OD of the pipe is 2.5" the actual ID of the pipe is a bit smaller.

A single 3" is like dual 2 1/4" so you should be plenty fine with that. Watch out for the 3" though because you need groung clearance to use them.....otherwise you could loose one going over a big bump.

The 3 inch will be replaced with dual 2.25, all the way back and two cutouts will be used like your set-up. My cars are low, I need clearance!!

I haven't yet activated the cutouts - I just need to wire them and I want it to look clean so I have to take my time - and right now with family in town I don't have the time to devote to doing the wiring.

However I can say that with the X pipe installed with 2.5" back to the stock resonators, I have picked up power everywhere. I think I picked up most of the gains in the lower RPMs. I can really feel it when I pull away from a stop light....this morning I was squealing the tires a little bit at about half throttle.

Up next is programming and the VB mod!

Oh and the exhaust is super quite, but just a tad louder than stock. at idle and part throttle is is barley noticable. If you didn't know you'd have no idea. At WOT you can tell it's there but it doesn't overpower the engine.

I have yet to hear it from outside the vehicle except when reving in neutral, but overall it is exactly what I wanted.

I'm just not understanding the 14.6 1/4mi time??? That's not anywhere near what it is supposedly suppose to run in stock form. I was hoping for some high 13's.I guess these cars just feel fast. I wish someone else had some 1/4mi times to post for their M45.At least something to compare to.

I was a little confused myself actually....untill I did a little more research.

I started searching around to find as many magazine articles as possible, and there were handfuls of comparison articles with similar performance numbers to mine. A little confused I went back to each article and looked at the publication dates - and sure enough the quickest times were pre and early production dates for the car. I'm thinking that the magazines just got the burly test mules in the beginning with the WOT restriction removed.

If you take a 4000lb car and put in a 200lb man and calculate the horsepower - even with variations from one calculator to the next you still need over 300rwhp to get there.

If you put in what I got 14.6 @ 97.69 and I have actually weighed my car with me in it down at the dump - 4280lbs it shows right at ~270 ~ 311rwhp depending on which method (et or mph) to figure the rwhp

This car is heavy!

and technically if I could pull a 1.9 60ft time (which would be possible easily) that's 3 tenths - and everyone knows time gained at the 60ft mark is near 1.5 time gained on the big end.

So I hate to say this, but "theoretically" I could gain almost a half second quicker through the 1/4 mile with just a better launch - give me the 3.69 ratio rear diff from an X model and stuff in a decent LSD unit and I'd think I'd be there.

Did you pull the harness off of the brake light that triggers the traction control?Just curious as you never mentioned that.When you getting it tuned? Has UpRev tuned one of these cars by now? I thought they already did?Maybe the power loss is rapped up in the tuning. Lets hope. I really would like to see the gains from tuning. That's about the last mod I will perform on my M. The VB mod is out of the question due to my purchase of the Elite service plan. Did you lighten the car as much as possible? When I always went to the track, I made sure every thing that could be removed easily, was taken out.Really the LSD is not needed. A set of drag radials would do the trick.

that's a really great setup good work
