I'm the friend with the Tanabe Concept G exhaust Justin mentioned. While it is a single outlet, in street class trim I've never been bothered by drone on any of the road trips I've taken. That includes Denver->Portland x2, Denver->LA, Denver->College Station, Denver->Lincoln x6. Any of those trips I made on RE71s had me cursing the tire noise though.

The thing to remember is that most will quiet down over time as they get loaded up with soot. At 20k/year, you'll see a big quiet down after just a couple weeks.

I like the sound of the Nameless delete that I've run for 4+ years, but I'd like to try something else because it was not that ideal and might have become more droney over the years.

It's nice to see your progress. I was on the other side of you at the Devens event and glad to see you fixed the positive camber. I like the look of the single Ft86 Factory system, but I heard it might be droney too?

Hey nice to hear from you!

And ya I had been looking at reviews for the nameless delete and I'm just too paranoid about the drone, if I can find the flange anywhere local I might just weld a 2 inch pipe downward to see how bad it is for race days.

Although I'm sure I wont want to take that stock exhaust on and off too many times.

Update time!

So after a lot of really good events the car is finally starting to feel planted in transitions and is really a joy to drive.

I also found that on my 235s If I go much below 35 up front, then on pretty much any turn, my car understeers like crazy, and does the front tire "shudder". 35-37 up front seems to be giving me the best response and times. Whereas the rears are typically at 29-30.

I think this is because of a couple of things, the first being that I was only able to get 1.2 degrees of camber up front with the stock bolts and with loosening EVERYTHING so I feel as though my car is just camber limited. The second reason I think is because of my 20mm bar on full stiff. I might try an event with it on the softer setting to see if it feels any better at lower pressures.

But all of this season has showed me that I really want to go to STX next year, so I already picked up the OFT and I'm going in for a baseline stock dyno on Wednesday before I start throwing on power parts. I'll probably test out the OFT at a few of the lax events, mainly for the rev limiter to try and get my top 2nd gear speed up a bit.

My goal is todo a budget STX build, under 6k I think, which won't get me first at nationals, but I feel should be competitive.

That's all for now!

I switched to a Blitz Nur-SPEC VSR dual exit exhaust. It weighs a bit more than the Tanabe but is really quiet with no drone. The extra weight is not a huge deal...

Also, I would put the money into the suspension/wheels first. Do engine stuff last. OFT/tune is probably the best upgrade for the engine for short term.
