Highflow downpipe and performance exhaust would be best.

I have both the GT HFC downpipe and performance exhaust. No CEL issue for me.

There are a few posters in the GT downpipe thread reporting codes thrown though.

Post a vid.

I'm getting the stock downpipe reinstalled tomorrow to do a baseline testing then put the GT downpipe back for a comparison.... it feels like I was having some issues with my first time installing the downpipe...

spideypm · 02-06-2013, 08:29 AM

I will gather the numbers and perhaps shoot some vids tomorrow

Balzz · 02-06-2013, 09:14 AM

spideypm, you will either save, or cost me another 700 bucks lol.

Currently it was only one person. At last check, it had actually gone off. We are working with the customer closely to solve the prob if it comes up again though. This is the only case we are aware of.

It's deeper but not raspy. I can hear it now inside the car but it doesn't "drone". The best part (obviously) is when I get on it hard and click off full throttle up shifts........YES! It sounds awesome...every shift delivers a race car like snort between gears and downshifts sound even better. Someone said this exhaust is "a lot of money for some noise" but for me, it was money well spent. The stock car was just tooooooooo quiet.

Hey Alpine,

I met you at that Mod Bargains meet. I was admiring your car as you parked. I finally did my ED and got my EBII F30 a week ago. I slapped on new wheels and tires at Mod Bargains last Sat.

I got the M-Performance exhaust, as well. I have about 800 miles on it and the sounds is only now coming in. And only really noticeable in Sport+. I'm still breaking the engine in and not rev'ing past 4000.

I remember. Wow your car looks awesome! Congratulations! I want to hear about your ED!
Lets meet up when you get your car all broken in. PM me.

Um..... While I'm trying to figure out how to post pictures and vids here..... Here are the numbers I got today... Here in Taiwan folks like to measure performance of the cars by timing 100KM to 200KM runs..... I got 15 sec flat running stock DP and 13.5 secs running with HFC DP.

Question: when doing runs? does putting the car in sports mode affect the timing vs. running the car in comfort mode?

of course...shifts are quicker, holds rev's longer, etc.
Sport/+ mode for true engine/handling performance...

nsquared · 02-07-2013, 11:45 AM

Sport+ mode in the snow = 360s breh.
