Either way, waiting for the new resonator to be swapped in. Will try to get a final update by end of week.

I know you're N52, but I have 200 ft-lbs of torque at 2.5k

Yea but there's a huge difference switching over to a single 3". For street I would've kept the stock pipes but I just cared about gains in the upper range where I normally lose steam on a road course. When I did take the car out on the freeway though it was a blast putting the foot down all the way to redline.

Y pipe placement needs work then. How big are the secondaries coming off of the header?

Y pipe is mounted directly behind headers so not much more room for adjustment / work. The headers are 2" and the Y is two 2" into 1 3"

And that could be too close.
I need a dyno.

Exhaust is pretty much done. The Vibrant ultra quiet resonator did the trick. Killed any drone / rasp while maintaining aggressive tone. Pick up car end of week and taking her straight to track. I'll be sure to record some laps. After driving her all weekend I'll decide if I still need to slap on a mini bullet muffler but as of now the final design consists of:

SS headers
Burns ss Y
Vibrant 1142 resonator
Flow master Delta 40 muffler
Pypes oval tip

I'd like to see an in car acceleration video. Is it all stainless steel?

Pictures...dyno?

Yes all stainless and mandrel bent. I'll upload some good videos from my track day coming up this weekend.

Car's been in shop entire time, been busy getting it ready for new season (suspension work in addition to exhaust). Like I said before I'll dyno if/when we can get others to come out else it's pointless to show my after without a before.

Same for me so more the reason to do it. 5 hours is max I'll drive but tracks like the Glen are worth it. Good length, mix of elevation changes and just the historic significance make it so awesome. Heck my friends and I are even considering going to Mosport in Canada in July.

Dad and I hauled down to Daytona last November which was 10 hours. A long haul but worth it to experience driving that track. I think we'll hit Watkins Glen next year.

3002 tii · 05-01-2015, 11:17 PM

Picked up the car this weekend and took her straight to the track. First event of the year so lap times were pretty slow but I was pretty happy with how the exhaust turned out.

andrey_gta · 05-04-2015, 04:16 PM

Sounds great!!

If you do come out to Mosport in Ontario let me know id come hang out and listen to that exhaust lol

Thanks under the lower revs the car sounds more throatier and has a nice burble when you let off. It's only raspy when I'm on throttle in the higher rpms (above 4,000). Here's cold start up:

sweet sweet inline sex noises. Sounds fantastic!

andrey_gta · 05-06-2015, 07:48 AM

How is the smell? Is it really unconfortable ?

Only notice it at a stoplight, any other time you can't tell

andrey_gta · 05-06-2015, 12:35 PM

So there is a chance I will just be catless and that it will be okay. Hmm
