Rob makes an excellent point. This is exactly what caused my last exhaust to fail. One of the welds tore out and then I ended up dragging the exhaust for two laps. This wreaked all sorts of havoc (the accordians then broke). Basically, I had to get an entire new exhaust from the manifold back. Rob’s solution (wrapping the hanger around to the underside of the exhaust) is smart. That’s the way my Version 2 exhaust works currently.
Spec Exhaust?

Directly from the rules:
9.3.4.1.2. The spec exhaust system components must be either welded or clamped together after all slip joints are fully seated.

[quote]One other question I have is this. Some tracks have restrictions and this will be a touch loud I’d bet. Can a car legally attach a turn down, steel wool in the tailpipe, dispersal tip, supertrapp, or similar to muffle the car further? It might be a good idea to have an approved spec method that racers can prepare for ahead of time or carry in the tool box. Some methods can be tuned and some simple testing would be easy early this season.
Also, the hangers attach from the top which isn’t a big deal. But if they wrap under the pipe and are welded on the bottom then the exhaust ‘hangs’ on them… If it’s welded on the bottom then it hangs on the steel strap or rod not a weld.
Looks hot otherwise, and now I know where all the illegal parts are under your car. ;)[/quote]
Rob and all:
The builder and I discussed this mount (prior to your post) and I do like the idea of a hanger that wraps around the pipe. I’m sure he can do it and I’ll make sure it is done that way.
Regarding the down-turn for noise-restricted tracks, we discussed this today as well. He’s coming up with a piece that everyone can use, that will only cost a few dollars and that will hose-clamp to the tailpipe. I’ll test a few this season, well before the June deadline.

…What it isn’t is expensive “car jewelry.” However, it’s resonably priced (about $170.00 plus shipping) and will do what we need it to do. And the car still sounds like a race car.
Again, I’ll talk with the vendor tomorrow and we should be ready to move forward.

What? :blink:
You show us video of a pan along the bottom of the car and no audio clip…
I’d love to hear it. but do we have any before and or after numbers?
Can it be welded in?
BTW: Thanks for posting[/quote]
I’m planning to get to the dyno this weekend. If I can get there, I’ll take my new Flip Video camera and will put a clip on Youtube.

Spec E30 Exhaust Announcement
Order info - Contact Paul Poore pepco2@verizon.net - Paul prefers email for now but I will post his phone number in the next couple of weeks. He is moving to a new shop and we don’t want to post the old number, and then the new number.
Cost - $175.00 plus shipping to your location. He could have used cheaper materials, crimped/non-mandrel bent tubes, and cheap clamps but we decided that a better design and durable parts are better than saving $15.00 on the price.
Future cost - As anyone involved in building materials knows, these materials are going up in price, regularly. Therefore, the price will probably go up some by the late spring/early summer. It won’t go up more than a few dollars but it will probably happen.
Availability - He has 20 sets right now and should be able to ship orders next week. We appreciate the current drivers waiting for the new car builders, who have no exhaust. And you have until June to get it on the car.

I just sent him an order email.
Out of curiosity, do we have to buy it from him (i.e. he is a sole supplier) or can we build our own based on rules?

He is sole supplier.
As I have the stock exhaust on my new build, I have sent a request for the exhaust so I am not out of the water if they are snapped up quickly. We are now 1 door bar, a transponder and fire suit away from done. Except for the damn license thing

FNG, building an E30 racer. Forgive me not going thru every post in the year since I last perused this forum, but…
Are we talking an exhaust system that leans toward some kind of custom-sourced solution? Something that a few “local” suppliers can make?
If so, count me out of specE30. The only reason I’d run this NASA class is to avoid these kind of sweetheart deals made by series founders and their buddy-shops. I don’t care what the cost is – it’s the principle that matters. I may as well run SCCA ITS (back of the pack, for sure) if I need to jump thru hoops to make the tail pipe comply.
Sorry for the beer-fueled rant. Just tell me if I have a reasonable chance of dealing with the exhaust myself – without having to go to a “spec-authorized” shop…

I’m not following this type of attitude. Every type of spec class has similar issues. You think the exhaust supplier is rolling in a Ferrari from spec E30 exhaust sales? I think not. Just don’t understand the uptight comments. It is not that big of a deal.
Look at the cost of Bilsteins and HR springs. They are considerably more expensive for the E30s because of SE30. What can you do, just comes with the game. As do rules, regulations, etc.
I just requested my system, hope he still has some in stock.

You cannot be serious with you comments about the HR/Bilstein prices going up. We are being forced to us a sole supplier for this exhaust system with is possibly the most ass-backwards piece of rule making yet. Many shops sell the suspension pieces and some have sales and others offer discounts to friends or long-time customers etc. We will be at the complete mercy of some unknown supplier in NC who could raise prices without warning because of whatever reason he states (new shop costs more, his metal supplier went out of business and he had to find a new one, etc). THERE ALWAYS NEEDS TO BE COMPETITION in the market.
Put the requirements for the system into the rules, ie specifications of pipe diameter, turn locations, resonator part number, etc and let the rest of us get the pieces made if we want. If I can have a local shop make me a system for $100 then why should I be forced to spend an extra $100 (75+shipping) to buy this one, it is ridiculous. And don’t feed me some line about how racing is expensive yada yada yada. Because it is expensive we should be taking every step possible to enable each competitor to manage his/her budget as best as possible. We are taking about a few tubes welded or bolted together, heck I bet Vic could make one of these with the tools he has from building his own cage.

bitch, bitch, bitch. It seems like every issue brings it out.
Live with it or head for your nearest Spec Miata group and see how much better it can be.
Carter’s doing a great job.
Spec E30, love it or leave it!

Seriously you’re bitching about a $175 dollar exhaust system. Frankly I was shocked it was that cheap.

It’s really not a bad price. It’s cheaper than the first legal exhaust I put on the car.
I’m just glad it’s finally available even though I’m waiting to allow all the nOObs to get their’s first. (read: over budget already)

Jon,
Not everyone can get a muffler system made and installed for $100. I’d be willing to bet that a lot of SE30 racers would be hard pressed to find a shop to make and install a muffler system cheaper. While I may not agree in the need for a spec muffler system I will accept it and move on. The objective for the new rule is parity among cars and this is a good thing.
(edit) Scotty, please go racing with SCCA. You’ll fit in just fine there.

I had a cat back system made for my prior track car, an Audi. It cost me about $225 installed. That was several years ago. The price for the Carter system is reasonable. Even if I could save $50 it isn’t worth my time to run around finding someone to make it for me.
I’m letting some of you guys get yours first. I’ll order mine in a month or two. Looked good to me in the video.
