Here's the thing on exhaust. Knowing SCCA and rules and stuff, go as light as you want (or that you can, depending on state rules and sound and all that) for an exhaust. Then, on the hangars, and/or the exhaust joints, weld on some lead/steel weights, or just on any of the pipes to bring it up to the 18lbs min weight.

Don't let exhaust weights and stuff get you wrapped around the axles on which exhaust to buy. Go with common sense, keeping in mind noise restrictions for your event site.

Yep, good advice. Was going to suggest just finding some weight to stick onto the exhaust to make it legal. Maybe some wheel weights with some heat resistant tape holding them on.

Why even do that? I'm thinking that you can just clamp on some weights to the Ti exhaust to make it legal now since material is open.

Remember lead melts at a pretty low temperature. I don't know if our exhaust gets to that temperature, but it might be better to weld or clamp on steel or stainless steel instead.

Lead: 621 F
Steel: 2500 F

Or, just put on a series of these?





(Seriously, they're exhaust components and around .88lbs ea.)

I saw someone on another site ask "what's to stop someone from adding weight" to a light exhaust to make it legal....like it would be a bad thing.

I already have a hard time caring how much other people's exhausts weigh to begin with, so *how* the exhaust makes weight is even less of a concern to me so long as It's not going to fall apart and leave parts on the course.

There really are very few legal exhaust options under $1,300 where making weight should even be a concern. I think people are making far too much out of this than they need to.

If someone is going to buy a really expensive titanium exhaust, the whole purpose of which is to get a super light exhaust, only to add weights to it to make it 18lbs and think that's the solution to winning, I'm pretty sure they're mistaken on what's really holding them back.

It's particularly silly when it's easy to figure out that you can achieve pretty much as close to 18lbs as possible with a Nameless single exit muffled track pipe on the stock midpipe, which will cost you all of ~$250 new and a lot less used.

Won't this turn into a protest nightmare with ballasting allowed (not that I am against ballasting) at nats? IE: you see someone running a titanium exhaust which would weigh under the limit, do you protest and get them to weigh all the ballasts?

[JakeRogue]

Considering I weigh 310 lbs I don't think I need to worry about how light my exhaust is. The real weight reduction cheat is how light can I become!

So we just close off the driver's side exit. Problem solved.

What's the point of even buying it then? An FT-86 SpeedFactory V2 axleback or Hooker Blackheart single exit axleback are both cheaper, very similar design, and don't require you to block anything off.

Just thinking of myself. I'm already running the Works resonated axle back.

Sell it and put a legal one on.

The FT86SF V2 axleback will require the FT86SF midpipe. The V2 axleback does not bolt on to the OEM midpipe. Just FYI for future reference.
